Exploration of caverns

So the party meets Ruark! Who is another scholarly half-orc from Riddleport. He appears to be someone who can take care of himself. If you know what I mean!

The party decides to continue to explore the caverns below the Glassworks that appear to have some relationship with the Goblin invasions and Tsuto's obsession with a hottie. Given the drawings definitely a hottie!

So they go back down and meet up with what is recalled to be a Sinspawn. A huge evil looking thing with a very large mouth!

Then they discover a large cathedral like room with a nasty bitch that has wings and fly's around casting spells at them. They finally take her out and shut her up.

What will the party do now? They have defiantly found some serious stuff here, right below Sandpoint! Will they continue to explore and find more loot? Will they go back and give the bad news to the people of Sandpoint? If they go to the bathroom into the orange lava pool, will it just disappear? Or turn into some noxious smoke that will kill them all!

She did not like invaders of her cathedral!
