The dragon Cthonyx has made an alliance with Lord Soth. The White Thorns fear to oppose him openly as long as Cthonyx is on Soth's side. Thelion Nightblade would like the party to find the dragon in the Great Chasm and remove him from the board. To reach his lair, she has suggested the group travel to Sumpfberg to search for the Chasm Crawler.
