As soon as they realized how summoning Skylanders works until they stop Hektore, Rainbow Dash tossed Twilight's crystal to Wendel, who cast the magic spell. Princess Celestia checked her selection for which Skylander to send, until she eyed a Dragon/Unicorn Hybrid,
"Whirlwind, you going with Rainbow Dash."
A holographic Whirlwind appeared on the portal as Princess Luna powered the Mini-Portal and connected it with Wendel's staff. In a few minutes, Whirlwind disappeared, Wendel tossed the Crystal back to Rainbow Dash, and Luna asked,
"We have to rescue the Mystic Seekers. Where are they?"
Wendel stuttered at Luna's question and soon said, "Well, there's Beaufort, he's somewhere in the Brighthold Battlements, next there is Tizwing, he's somewhere in Rivenrock Caverns, the third Seeker is Esmerelle, she's somewhere in Whitefall Summits, the Fourth Seeker, Humfry is in the Faylair Jungle, But I have no idea where my father is. My father and the other four Seekers are the only ones that could power the Shattering Sigil."
Rainbow Dash asked, "The Shattering What?"
Wendel repeated, "The Shattering Sigil is the image that is on top of the Sanctuary. My Father developed the Sigil, and it was supposed to be used as a weapon to destroy the Dark Mirror."
Rainbow Dash replied, "If that Sigil could help us destroy that mirror and keep Hektore from ressurecting Malefor, I could do this with both wings tied behind my back!"
Wendel got out a rope, but Rainbow Dash replied, "I didn't mean literally!" She facehooved and said, "Swap" And Whirlwind took her place. Princess Celestia recalled,
"All the other areas can't be opened until we have enough Radiance Crystals. The only area available is the Brighthold Battlements."
Princess Luna finished, "If Rainbow Dash and Whirlwind find enough Radiance Crystals, their energy would open the other areas."
Wendel added, "You need to open the other areas once the Crystals' energy is transfered to the Sanctuary."
Princess Celestia turned to Whirlwind, "You and Rainbow Dash better get going. We'll stay here and find anything more on the Shattering Sigil and the Dark Mirror. You need to work your way through the battlements and find Beaufort, so he can power his part of the Sigil."
Whirlwind nodded, "I understand your highnesses, keep an eye out if we have enough Radiance crystals to open another area."
Luna replied, "We'll know, but remember the word to have Rainbow Dash take your place."
Whirlwind replied, "I will."
With that, Whirlwind jumped into the portal leading to the Battlements. She appeared at a Proving Ground and was soon attacked by Cyclopses. Whirlwind used her Rainbow ability and Storm clouds to set them up as airborne mines. Whirlwind collected these little vials and felt stronger by the minute, so she knew it was time for her friend to play,
"Swap!"
Rainbow Dash took Whirlwind's place and used her ability to create a Rainbow Ring and hurled at her attackers, she collected more of those vials. But now Hektore was coming,
"Oh great, and there's no exit. Maybe I should defeat more of these creeps or collect more of those vials, an exit should appear."
Rainbow Dash did both and soon an exit portal appeared just before Hektore nearly catched her, but she made it through in time.
Rainbow Dash and Whirlwind returned to the Sanctuary to ask Wendel about those little vials. Rainbow Dash asked,
"What are these things? Everytime we pick one up, our power increases."
Wendel replied, "These are Radiance Energy, these can be used to revive defeated Skylanders or using Magic items." He turned towards the gate, "There is also Elemental gates, these are connected to Skylanders of one of the 8 Elements and there is a Life and Water Gate in the Flooded Viaducts of the Battlements. This is my only hint about the Elemental Gates, the rest is up to you."
Rainbow Dash now requested to swap out for some other Skylanders, The Royal Sisters were doing the same routine as before, Celestia selected a Skylander, Luna connected the Mini-Portal with Wendel's staff and a new Skylander appears.
At the Flooded Viaducts, Fluttershy and Gill Grunt were popping balloons with his harpoon, Fluttershy was staring down the chompies into falling over and finding the Water and Life Elemental Gates, but what they didn't know is that when Hektore comes after them, he absorbs their essence from the gates, if they been in there before.
After Drobot and the new Fire Skylander, Spitfire rescued the Seeker known as Beaufort, in the Dream Gardens, they returned to the Sanctuary to find that Beaufort powered his part of the Shattering Sigil. He even got the chance to introduce himself to the Skylanders and the Royal Sisters.
"My name is Beaufort, Archivist and Mystic Seeker of the Radiant Isles. I never thought the day would come when I would be rescued by a Portal Master, or in this case, two Portal Masters...from Equestria. Now this is just rare."
Princess Celestia introduced herself, "I'm Princess Celestia, Goddess of the Sun and Co-ruler of Equestria." Princess Luna went next, "I'm Princess Luna, Goddess of the Moon, and Co-ruler of Equestria. We are also Portal Masters, hand-picked by Eon himself."
The Archivist was intrigued, "Fascinating, when this is all over, I heard of a reigion just East of the Radiant Isles called, 'The Equestrian Isles' is that true?"
Princess Celestia replied, "With the Bridge between our worlds connected, that rumor is real."
Beaufort was excited, "The Equestrian Isles are real, and once this is over, we could visit the Isles."
Drobot replied, "Well, you're here, your part of the Sigil is powered up and another area is opened."
Spitfire noticed, "The Holiday season is near, so after this, maybe we can invite you guys to a Christmas party."
Beaufort replied, "The other Seekers will like that."
Princess Celestia said, "We will save the Radiant Isles and then we will prep for our Christmas Party."
Drobot and Spitfire entered Rivenrock Cavern, entered Elemental gates of their Element, got chased by Hektore on some occasions and rescued Tizwing.
Rarity and Fluttershy entered the Whitefall Summits and rescued the Seeker, Esmerelle.
Applejack and Camo entered the Faylair Jungle and rescued the Seeker, Humfry.
Chop Chop and Ignitor journeyed to the Galecrack Ruins to rescue the final seeker, soon they discovered that the final Seeker is Fargus. They were shocked on discovering that he's still alive. But after they rescued Fargus, Hektore appeared right in front of them and took him away. Ignitor told his Undead companion,
"We better get back to the Sanctuary and tell Wendel and the Princesses about this."
Chop Chop nods, "Good idea."
As the duo returned to the Sanctuary, they went to Wendel and the Princesses, Ignitor spoke,
"Fargus was there."
Wendel asked, "My Father is alive!?"
Chop Chop replied, "He's alive, but Hektore got to him before us."
Celestia realized, "You have your Father's staff, you can power his part of the Shattering Sigil."
Wendel asked, "Take my Father's place?"
Luna replied, "Without Fargus, its up to you. Besides, you are the last 'Free' Seeker."
Wendel frightenly said, "But I haven't completed my Seeker Training!"
Celestia assured the Apprentice, "We have faith in you, Wendel."
Luna continued, "By your Father, We have faith in you."
Wendel said, "Ok, I will try. By my Father, we will destroy the Dark Mirror."
Celestia requested, "We want to switch Skylanders."
Wendel replied, "Ok, You might want to switch up to others before the confrontation."
Chop Chop tossed Ignitor's crystal to Wendel, Celestia chose Spyro, while Luna linked the portal to Wendel's staff, and Spyro appeared in the Crystal. Spyro tossed Chop Chop's crystal to Wendel, but this time, Luna chose Spike and Celestia linked the Portal with Wendel's staff and Spike appeared in the Crystal.
At the Dark Mirror, Hektore was floating around knowing that the only Element he's missing is Magic,
"Malefor's return is depending on that last element, but no Magic Gates were opened by any Skylanders."
But Hektore knew that they were coming along with two Magic Skylanders, Malefor's return is coming.
