I don't want to look around the boards too much and spoil stuff inadvertently, but could someone give me a hint on what needs to be done next in the Abyss? So far, I've found a big whale that doesn't attack me, a door that needs to be opened with an energy-charged orb, a weird bluish tentacle thing that seems to be plugging up a tunnel, and an artificial barrier that prompted Naija to comment on it seeming familiar (which it does, but I can't remember where I saw its marking).
I'm coming back to the game after being on vacation for a week or so, so I forget exactly what I was doing. Without giving anything away completely, can you give me a hint on which of these possible things I should be focusing on figuring out first (assuming it matters)? Thanks for your help!
