Hi

Im going to run green eyed boy but, I'm struggling to understand how the events fit together?

Who are the witchs

What dose the butler want

Whos the. Old man with the noose

And why is there a portal to a cold land.. Who opened it?

I haven't try story 5 yet. But if you are facing error in the story then you should probably check Mansions of Madness errata. There's 2 fault in the map. Sorry I couldn't point it out to you which one because I don't have the game with me right now.

It's awful,

AVOID AVOID AVOID AVOID!

GEB has produced the two single best game experiences I've ever had. But using "that one objective" will probably kill your fun quickly.

Witches are able to move between dimensions, which explains HOW they do what they do. Who they are is left rather to the imagination of the players. Thematically, it's rather objective-based.
