Also once you finish the Vera quest, I think that activates yet another quest line from the wheezing dude Abrahm at the Junktown bar (when you enter, with the merchant who sells all the food). I think I finished the game, the only part left is that weird obelisk when you take the boat to the silent Isle (it should still be there in 1.7.0). That part is pretty hard (dopplegangers...), and also I think you need a character with strong willpower to deal with the obelisk. I'm so curious as to what happens, but I never managed to create a high willpower character.
