Okay, I'm very busy with my thief guild, and i have like 3 major subquests left. I'm currently working on the Firkraag one, and its getting anoying. Sorry, but i have another question. Does Firkraag time you to complete his challenge??
When i go to the (SPOILER) Underdark, and Saughain city, will i lose my stronghold because i'm not there??
Also, for those who played a druid, and completed SoA with one, what are the benefits of being a "Great Druid" any bonuses, resistances??? All help is welcome, thanx.

No you won't lose your stronghold. Don't know about druids, never played one.

You get 20,000 exp and some gold and items for becoming the great druid. Other than having the title I don't think you get any other benefits. I played a druid and got 14th level right before I finished the game so my druid is in ToB and I have no way back to the druid grove, so I don't know if there are any sub quests involved with being the great druid.
