Legend

You begin feeling the walls looking for a passage of some sort and just like you anticipated you find one and hear a click. You follow the passage hoping it will lead to someplace good.

Naturally it doesn't.

You eventually come to a candle lit room with a metal table in the center. Dried blood stains the floor. Bones litter the floor as well. Some lab equipment lines the walls along with some old tomes. There's another dark corridor leading off to somewhere across the room.

It's probably also worthwhile to point out that there's a girl with ripped clothes tied to the table that sees you and whispers for you to help her.

"Stranger! Please! Help me! He'll be back any minute! He's a sick madman! A necromancer! I don't want to die!" she says.

Looks like you stepped into something a lot more serious than you thought.
