As Spike left the room Twilight turned to the others and says to Rainbow Dash " Rainbow i need you to help me get to the empty meadow behind my castle. As for the rest of you. You need to get some well deserved rest and relaxation. So are you ready Rainbow Dash?"
Rainbow looks at Twilight with shock and says "Sure i am. I'm just surprised that you like mares."
Rainbow Dash then helped Twilight out of the hospital and after half an hour of walking, mainly because they didn't want to risk flying they arrived at the meadow.
Upon reaching the middle of the meadow Twilight turns to Rainbow Dash and says with confidence and sincerity " Thank you Rainbow for helping me get here. However for this spell to be cast i need to be alone. I'm so sorry if I'm making you worried, But it won't work if I'm not alone. Do you understand?"
"Of course Twi. Just know that i don't like leaving you alone like this. I will though because i also care about Rose. I feel like she is a sister to me. Just be careful,"says Rainbow taking off.
Once Rainbow Dash was out of sight Twilight focused all her magic and love for rose into her horn and says " Latua Enchancia Truelove Immortalia." As she finished the spell there was an insanely strong and powerful burst of rainbow magic from her body.
Twilight felt an intense pain she has never felt before as all her memories of rose and her feelings for her were scanned. After five minutes of the pain it ended and she felt exhausted. As Twilight opened her eyes she saw that she was no longer in the meadow and in front of her stood an alicorn mare she has never seen before.
The unknown alicorn had a pink coat, rainbow colored mane, eyes as bright as the morning sunrise and a sky blue tail. The alicorn looks at Twilight and says "My dear my name is Immortalia. There is no need to introduce yourself. I know who you are Twilight Sparkle for i exist outside of time for i am the guardian of Immortality. Please tell me what can i do for the Princess of Friendship and bearer of the Element of Magic."
Twilight was surprised that the alicorn knew who she was. However Twilight got over it quickly and says in a Confident but worried tone " Immortalia your highness. I am here to request that you tie my immortality to the mare i love. She is currently in Ponyville General Hospital with only a thirty percent chance of living. I beg you please save her. Her name is Morning Rose and it is because of her that i am who i am today. I feel as though half my soul is dying." As Twilight finishes talking she breaks down crying.
Immortalia walks over to Twilight and gives her a hug while rubbing her back. After ten minutes of calming Twilight down she says " I can save Rose but first you must pass five trials. A trial of skill, a trial of strength, a trial of heart, a trial of courage and a trial of sacrifice. Once you pass i can make her immortal and tie it to you. However should you fail even one trial then you will die and your soul will be destroyed. Are you willing to take the trials to save the mare you love?"
Twilight looking determined looks at Immortalia and says in a voice of pure determination and confidence "If i can save the mare i love than i do. She is my light when all i see is darkness. I want to marry her and live happily together forever. With out Rose my life has no meaning. So do your worst Immortalia."
Immortalia looks Twilight in the eyes and says " Your first trial is the trial of courage. If you follow the trail to my right you will come across a river with a bridge. To pass the trial all you must do is cross the river with out magic."
Twilight with out hesitation gallops down the trail. After five minutes of hard galloping she come to the river and bridge. As Twilight approaches the bridge a sign appears out of no where.
Twilight reads the sign out loud to herself saying "Beware for who so ever crosses this bridge shall never return."
Twilight takes a deep breath and walks across the bridge. As she neared the end of the bridge Twilight saw that here wasn't anymore planks on the bridge. Twilight knowing this is a trial of courage continues walking. A couple minutes later Twilight was across the bridge.
As Twilight looked behind her she saw the illusion hiding the end of the bridge vanish. Feeling relieved Twilight turns around to see Immortalia standing five feet in front of her with a smile on her face.
As Twilight approached Immortalia says " Congratulations Twilight. You passed the Trial of Courage with flying colors. Your next trial is the Trial of Strength. To pass this trial all you need to do is lift this rock above your head with out magic." Immortalia stepped to the side revealing a rock the size of a diamond dog.
Twilight approached the rock and took a deep breath and used all her strength to lift the rock. At first Twilight struggled for a few seconds but all of a sudden she lifted it without any trouble. It felt as light as a feather so she threw it in the river.
Immortalia upon seeing the rock flying through the air says "Oh my Celestia. That is so shocking. You see Twilight that rocks weight even though it was small was the same weight as ten heavy carts. However it was enchanted to become lighter based on the trial takers inner strength. Those who passed this trial before you could only lift it above their head. You are the first pony to ever be able to throw it like it was nothing. However it is now time to begin your next trial. Your next trial is the Trial of Heart."
Twilight looking confused asks "How am i going to pass this trial?"
Immortalia looks twilight in the eyes and says "To pass this trial all you need to do is confess your feeling to Rose. I'm going to summon her spirit here the rest is up to you."
As Immortalia finished talking her horn glows and Rose appears in front of Immortalia and Twilight.
Rose has a look of fear on her face as she looks around. However as her eyes fall on Twilight she runs over to her and asks "Twilight wh-where are we? The last thing i remember is the train being attacked by a dragon."
Twilight after taking a deep breath says "Rose everything is fine. However i have something important to tell you. You are the sun that warms me in the winter. Your are the light i see when all is darkness. You are the sun of my life. I love you my dear Rose. I always have. You see I like other mares romantically. The day i first saw you at Celestia's School for gifted Unicorns was the day i fell in love. Even though you were a colt at the time i still loved you."
Rose had a look of surprise on her face. A couple minutes later she calms down enough to say " I love you too my TwiTwi. I always have."
Immortalia after hearing the exchange of confessions says to Rose "Rose my name is Immortalia. Twilight is here on a mission and i am the one who summoned you. She has passed the trial. However i need to send you back now but know that i will summon you again." After receiving a nod from Rose Immortalia's horn glows and Rose disappears.
Twilight about to start crying says "I'm ready for the next trial."
Immortalia looking pleased says " For your next trial which is the Trial of Skill you must enchant these rings with a detection and protection spell. How you do it is up to you my dear."
Twilight having perfected her own unique detection and protection spell a month ago says "Okay I'm ready." After taking a few deep breaths to calm herself she says " Detanio Protentcia castano un Ringana." All of a sudden there is a flash of rainbow magic from Twilight's cutie mark.
A minute later Twilight and Immortalia regain their sight from the blast of magic. What they saw was a surprise. Both the rings were glowing with a bright rainbow.
Immortalia being the first to recover says " Very well done Twilight. That is the strongest i have ever seen. Now it is time for the final trial. The Trial of Sacrifice will be difficult but i believe in you Twilight. The Trial of Sacrifice must be performed in front of your supposed true love. That means I have to summon Rose, are you ready?"
After taking a deep breath to ready herself she says " To be honest Immortalia i am scared. However if i can save Rose then yes i am."
Three minutes later Immortalia had summoned Rose. As Immortalia looked at Rose she says " Rose This is Twilight's final trial. It is called the Trial of Sacrifice and it needs to be performed in front of you. All you need to do is stay quite and watch."
"If i can help Twilight in anyway i shall do whatever i can to help. After all i love her,"says Rose with the most adorable blush on her face.
Immortalia nods at Rose and turns to Twilight and says " Twilight to pass the Trial of Sacrifice you must sacrifice your three most treasured items. The first is your magic. The second is your immortality. As for the final one it is your life. If you are willing to do this to save the one you love then touch this sword." As Immortalia finished talking a sword dripping in blood appears.
Twilight to save Rose walked up to the sword and touched it. The moment Twilight touched the sword she felt exhausted.
Rose was watching Twilight with shock and horror on her face. The moment she saw Twilight touch the sword she ran forward to Immortalia saying " Please take my magic and life instead of hers i beg you. Equestria and especially Twilight's friends won't survive without her. On the other hand my life means nothing to the protection of Equestria."
Immortalia nods to Rose and says " Fear not. For this trial was for both you and Twilight to see if both of you would be willing to sacrifice yourself for the safety of the other. Both you and Twilight will be unharmed. You have both passed with flying colors."
Rose runs over to Twilight and says while crying " TwiTwi wh-wh-why are you so willing to sacrifice you magic, Immortality and your life for me?"
Twilight says before passing out " Because Rose with out you my life has no meaning.I care about my family and friends but they will move on. I also saved you because out of everypony i know you are the one that has the potential to help others like you be true to them selves."
Immortalia saw the look of worry on Rose's face and says " Rose. Twilight under went these trials to save you. You see in the real world your body is dying. You only have a thirty percent chance of living. So Twilight cast a spell to bring her here to make you immortal. I am proud to say she has passed with flying colors. So with your permission i will cast the spell to make you immortal."
Immortalia after receiving a nod from Rose says " Immortality Incantato Insento Tana Rose."
Rose's body glowed bright then faded.
Immortalia sent Rose back and waited for Twilight to awaken.
