Slay Kaah and report back to Veleslav Kapishev.
Another horrible beast has been created by the curse. Kaah, a terrible hydra, has appeared at Arrowsong Crossing. It's not only the merchants that can't pass through there - even the Defenders avoid those parts. I tried to talk to Dobrinya, their commander, but to no avail. You're our only hope!
I believe that you can do it, especially after all the exploits that the entire Settlement's been talking about! The people are starting to say that the hero of Kania has been reborn and they're talking about you, not the White Knight! Well, can you help us out?
A hydra is certainly not as bad as, say, a demon, but not by much!
