Soon the trio arrived back in Equestria and saw Princess Celestia waiting for them. The boys were a little confused though. Why would Celestia be waiting for them?
"Welcome back boys. Did you have a good time with Sunset?" Celestia asked.
"Yes we did Celestia. But what are you doing here?" George wondered.
"I came here to talk to you about something you may need to be careful when facing another villain. Twilight, Sunset you may leave us." Celestia replied.
So Twilight and Sunset did what they were told to and at the same time Luna came in. She too needed to inform them about Tirek.
"So boys. Your wondering why we needed to talk to you." Luna said.
"Yes. Were not in trouble are we?" Harold worried.
"Oh no not at all dear. See we needed to talk about another villain you should be aware. You got lucky defeating King Sombra and Queen Chrysalis. But the one villain you gotta be careful is Tirek." Celestia replied.
"Who's Tirek?" George asked.
Then the two sisters lit their horns and began explaining everything about Tirek.
"A long time ago Tirek and his brother Scorpan came here from a distant land, intent on stealing Equestrian magic. But Scorpan soon came to appreciate the ways of Equestria, even befriending a young unicorn wizard." Celestia started.
"Scorpan urged his brother to abandon their plans. When Tirek refused, Scorpan alerted us to Tirek's intentions." Luna added.
"Scorpan returned to his own land, and Tirek was sent to Tartarus for his crimes. But it appears he has found a way to escape." Celestia replied.
"We believe something happened when Cerberus was still at his post at the gates." Luna theorized.
"But you said that was a long time ago. Why is he just now starting to steal magic?" George asked.
"His time in Tartarus left him very weak. He has just now gained enough strength to use his dark powers." Celestia answered.
"But with each passing moment, he grows stronger still." Luna finished.
"Oh that is bad. Wait how do you know this happened in the first place?" Harold wondered.
"Because I had a vision of him escaping Tartarus through a portal. So boys. If you encounter Tirek be careful." Celestia replied.
"We will Celestia. Promise." George said.
The sisters smiled and headed out leaving the boys. Then Twilight and Sunset came back in and asked them what they spoke about.
"So what did the princess say boys?" Sunset wondered.
"Well she explained about a centaur named Tirek and that if we managed to encounter him later on we need to be on our toes." Harold replied.
"Good thing she did. Tirek caused a lot of trouble the last two times me and my friends faced him. He even destroyed my old house one time." Twilight agreed.
"Man he is really that cruel?" George asked.
"Oh he is. He doesn't care about anyone but himself. He can even steal your powers if your not on guard with Captain Underpants." Twilight answered.
"Then we will make sure that we bring our A game." Harold decided.
"Were glad to hear that. And I heard that you two make comics. Any chance you can make one with the evil Tirek in it? I would love to see how your hero stops him." Sunset asked.
"Well we do like making comics. Sure we can do that. But after we go find some rings at the jewelry store." George replied.
"Any reason why?" Twilight asked.
"Because we thought about what Sunset said. And we think that if we get them now then we can propose to Lyra and Bon Bon for marriage." Harold answered.
"So you do wanna marry them?" Sunset said surprised.
"Yes. But we wanna wait til the right moment. Come George let's go find them some shiny rings so we can propose at the right time." Harold said.
The boys headed out to the jewelry store to find two rings to propose to their girlfriends when their ready to ask them in marriage. Twilight and Sunset smiled seeing the boys growing up so quick.
"They will make Lyra and Bon Bon so happy." Twilight smiled.
"They sure will Twilight. They sure will." Sunset agreed.
Meanwhile deep in the Everfree Forest we see Tirek building something out of all the tech he took from Melvin. He wasn't finished because he doesn't know what he wants it to look like when it's done. He paused for a moment to think and he did.
"Hmm to really destroy Twilight and her friends I need to know what weapon I want it to be. Like a mech suit, or a laser car, maybe even a good robot army. No all that doesn't sound good. Maybe I need to steal some magic from the ponies in Manehattan to clear my head." Tirek said.
So he took a break and headed out for Manehattan to start stealing the magic from the ponies to be stronger. That is sure gonna alert the princesses and the boys. What will they do to stop Tirek?
