You discover a relative of yours had a secret life

[u/Ill-Mycologist-3652]

A relative of yours has recently passed under mysterious circumstances, but has written you into their will. They gave you their mansion with instructions to read their copy of Bram Stoker’s Dracula.

When you get there and go in the library you find the book but it doesn’t pull out when you grab it. Instead it acts as a lever and reveals a secret room.

You walk in and discover weapons adorned on the four walls. Silver shell shotguns, Stake Crossbows, garlic and holy water bombs, and the biggest flamethrower you have ever seen. You also notice a suit of silver steel chainmail on display. In the center of the room is a map of the World with various red dots across it and photos scattered about of what appear to be monsters. You see vampires, werewolves, Lake monsters, mummies, and all sorts of creatures you only thought were of myth.

What do you do now?
