Bit confused about what to do in the black egg temple (spoilers)

[God Snek]

Hornet (or whatever the lady with the needle and threads name is) told me to go there and... Now i'm not sure what to do.

I'm fairly certain that this area is going to be one of the later goals in the game. Keep exploring elsewhere and the key to the temple should become more apparent.

Keep exploring, you can't do anything there for now. You need to find some way to open that door with the three masks, but you won't know how to until you discover a certain area.
