I was feeling greedy, so after I got Khoth's spells and the Beastslayer Bade, I killed Sulfras and looted everything i could get to within his lair.
Now, here's the problem: magic map reveals a gigantic chamber behind his main lair, which walk-through walls lead to BUT there's 3-ways in, with impenetrable locked doors at each.
I may be wrong, but I think there was a triggered special talking about a keyhole for one of them. So, CAN I get in, and if so, how?
Thanks!
Edit: Sorry, search didn't turn up the other thread the first time I checked. Since I can't delete this post, let me also ask: did anyone else kill the dragons, and was it worth it/did it change the plot?
