Daring Do and the Cave of Skulls

Daring Do had now made it to her destination: The cave. The Cave of Skulls.

Legend has it that inside, there was some way you could travel to Tartarus, where Tirek was banished. If Daring lived, she wasn't gonna let Tirek out. But he might come out somehow... some other way... But she wasn't gonna let that happen. Nuh-uh.

Anyway, some say there's a map on the cave walls. Some ponies think there are magical teleportation devices hidden there. And some say there's a magical portal and some evil Centuar is gonna pull you in.
But Daring Do couldn't let anything bad happen. She was going there. She was getting that skull.
That skull was why they called it the Cave of Skulls. If you go to Tartarus with the cave, you will come across a skull. Bigger than any other, and only one eye. He was once Sombra's, but ran away, and he was the one who discovered the way to that prison. He may be dead, maybe no one knew what he was, but he still has power. There is a certain spell that will unleash it.

And so, Daring stepped in, and in no time, everything was dark.
