One of the mountains in Deus ex Lithos. Kubatka seems to be topped with a giant black lizard head, and infested with black kobolds. The Chosen of Kubatka seem to be the worthy warriors from these kobolds.
The Group first thought Kubatka was a person. It wasn’t until they talked to Neemus that he mentioned he knows of it from travelling through Deus ex Lithos. The kobolds in the cemetary and Rick “the Bandit” had a shrine to Kubatka.
