A volcano giant's enLIGHTenment

This island is awful. We decided to head down the caldera to follow the crew of the Zephyr. As we made our way lower, our path was blocked by a massive 18ft tall humanoid. Others called it a giant, it called itself Uder Conbar. Uder is a volcano giant who was from the elemental plane of fire (the awful opposite to my home plane). He was not aggressive and explained that he was tricked to remain here by the Duke who is an Efreeti. I explained that Efreeti are basically fire genies who, while tricksters, are incredibly malicious in their twisting of others' desires. Either way, Uder had no ill will for us and allowed us to cross... as long as we didn't step on his shadow. The big lug thinks that their soul casts the shadow and is part of it. Does he not know anything about how light works!? Torrielle pushed me along before I could explain it to him. Before we could make it to the bottom of the ridge, the ground gave way beneath us as a flaming Bullette attacked! It seemed to want some metal from us, and by us, me! The damn thing nearly killed me if it had not been for Kalibek's inspiring words. In the end, Uder came to help and the thing fled back to the caverns below the volcano. Hopefully we do not need to deal with it again.
We made it to the tree top of the caldera when a landslide rushed us down. We all came out relatively unscathed but learned some new tricks (LEVEL 6 BABY!!)
We eventually made it to the small pond and found an even worse smell. It turned out to be the bodies of 4 pirates, one of them identified as Captain Alyssa Brand. Before we could do more investigating, we were attacked by two trolls! Algar wanred us to use fire to defeat them so Torrielle cast her flaming sword. I tried my best to help but the rest of my crew were in perfect sync. Using Kalibek's magicwhispers to drive 1 of the trolls away, the crew easily dispatched one of the trolls and took down the 2nd when it returned.
We were going to check out the bodies and pond when several dozen crab like humanoids rose out of the pond and surrounded us...
