Two chapters in one evening! :D Enjoy, guys! I'm in a hurry to post this so I can finish watching the MLP episode on the other tab I have open right now. :P

Right about that time I heard hooves stamping through the door. I looked up and was almost knocked over by an obviously hug-starved Pinkie Pie. "YAY! We found you!"

The rest of the Mane Six, directly behind her, did not look nearly as happy to see me.

"Where in Equestria were you?!" Rainbow Dash demanded.

Applejack looked ready to buck me in the face. "Do you have any idea how scared we were?"

"I found Twilight," I said stolidly as I tried to free myself from Pinkie's death grip.

Immediately I had those ponies' undivided attention. They swarmed me. "Where?" "Is she all right?" "What happened to her?"

I held up my hands and they quieted down. Briefly I explained what had happened. "Didn't you see Derpy trying to warn everypony?" I asked in confusion.

Rarity sniffed disdainfully. "She said something about an angel wearing an alicorn necklace warning her about King Sombra coming back…nopony believed her, of course. Where in Equestria could there possibly be an angel…wearing an alicorn necklace…" Rarity's voice trailed off as I unfurled my wings, flipped my necklace, and glared at her. "Oh…yes indeed…"

"But what can we do now?" Fluttershy asked quietly.

"We've got to find whoever's destined to be the fifth alicorn." I touched my necklace. "Only she could bear this much magic. Only she can possibly be capable of saving Equestria."

Then it hit me. "I've got it!" I cried in excitement.

Rarity glowered. "This had better be worthwhile after we spent hours turning Ponyville upside down to find you."

"No, seriously! The prophecies say that the fifth alicorn was not born with her alicorn features. We know it can't be one of the current princesses because they're all present alongside the fifth alicorn. The new one has to be another kind of Equestrian creature—one nopony would expect to be the one."

"What exactly are you sayin'?" Applejack asked.

"Think about it! What Equestrian creatures carry the most magic inside, but are not alicorns or even ponies?"

The others looked at each other, then back at me and shrugged their hooves.

"You really don't know?!" I couldn't believe it.

"Why don't you just tell us, darling?" Rarity suggested.

"Sirens! They're some of the most magically gifted creatures in all of Equestria. Even Twilight had trouble defeating them when they were banished to my world, where Equestrian magic is weaker. They aren't ponies and they certainly don't have alicorn features or alicorn magic."

The Mane Six just looked at me for a second. Then all of them burst out laughing so hard I thought they were going to burst.

"Seriously?" Rainbow gasped. "You think the prophesied alicorn is a—a SIREN?!" She fell onto her back and guffawed beyond belief.

"You can stop now," I grumbled.

Applejack finally wiped the tears from her eyes. "Well, we certainly don't think it's a siren. What else is in that there book, T'ara?" Again she said my name like "tiara".

"That's all that I could find about the fifth alicorn princess." I sighed. "But if she's not a siren…who else could she be?"

"Twilight would know." Fluttershy looked mournfully at the floor.

"If we save Twilight, can she help us find the fifth alicorn?" Rainbow wondered aloud.

"I think the prophesied alicorn is the only one capable of saving Twilight at this point. She's chained up with King Sombra's magic. Only alicorn magic can undo the spell. And all the alicorn magic in Equestria is right here." I tugged anxiously on my amulet. "What's more, only an alicorn with magic in her can get the magic in or out of this amulet. Right now all four princesses have given up their magic. It's sealed in here till we find the fifth."

"But how will we know when we find her?" Applejack pointed out.

I smiled peacefully. "We'll know."
