I have multiple quests for the area of Hossberg, however; whenever I try to go there, regardless of method, (fast travel / eluvian) it auto starts the main quest - Fire & Ice. I can not access the companion quest for Taash, or kill the champion demon as required for a couple of other quests. Is this a bug? How to do Hossberg quests without starting Fire & Ice.
If you have an earlier save without having to go back too far, it helps to do all of the available companion quests and as many of the factions and regions quest as possible, before you do any story quest. Story quests often advance the main plot in a way that makes previous quests unavailable, and in some cases, being on a particular stage of a story quest can block you from doing a quest (because the story quest "takes over" the area). I know that isn't a satisfying answer, it's just how things work with this game.
I'd rather do them before, so I can go from 37 to 40 and have a better chance @ fire & Ice, I seem to constantly die !
There are some quests that are automatically started when you go to the relevant zone; I think this might be one of them. I'm not sure whether Taash's quest will still be available afterwards, since it's (iirc) for the dragon lair, but you should be able to do other quests in Hossberg after Fire & Ice.
