Thankfully for Thersys, after the dragons died the lava cooled off pretty quickly - apparently at least a bit of magic was involved in the process that allowed dragons to spit it out.

Suddenly, your thoughts relating to the battle are interrupted by slow but loud clapping. "Splendid, truly splendid battle. Could use a bit less blood being spilled on your side, but splendid none the less," the speaker, a raven haired eladrin who appeared literally out of nowhere, stopped his clapping for a moment to rise his hands and show that they were empty.
"Ah, but excuse my rudeness. My name is Paelias, and I'd wish to take a moment of your time... heroes."
