1. I also entered Stormfist castle at this point.
More quests in Dark forest will be avilable after going to castle.
2. No quest.
3. The cave with lich in it?
No quest, just a royal sword and polymorth spell book. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
4. You get the quest when you open any treasure map.
And you'll get the quest to find the treasure cave once you collected all maps.
You'll get pyramids soon enough after going to Stormfist castle.
There's no real quest in Verdistis sewers, maybe part of the quest can be completed there, but there's lot of exp. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
5. In the gem quest you just have to watch the cut scene to finish the quest.
It's normal Boratus escape.
One quest in Dark forest will be connected to him again, then you'll have the chanse to kill him.
