Trapdoor

Coming back to The Book Of Elsewhere Olivia finds herself having to go in the basement the creepy dark basement. When she went in the basement she knew something was watching her she turned around and saw a pair of green eyes looking at her and she found out it was a black cat sitting on wood, but the floor was stone. Olivia talked to the cat and found out that the cat was guarding the trapdoor. I think that the trapdoor has something that Olivia will have to face later on in the story if the cat is having to guard it but I want to know what she will do if it is something bad inside the trapdoor.
