Stryker describes what he saw:
Crystals There is a large glassy mass that covers a section of rock that is sprinkles with small sections of a luminous pale blue stone. The glowing bits look similar to the other crystals you collected but you do not recognize the glass like mass.
Dust cloud it swirling. Feeling a warm breeze you assume there is some kind of volcanic vent in the middle or some other phenomenon is causing the effect. Keeping clear you move on.
Your search bring you to a region full of large cracks and canyons. sharp crashing sounds echo through the caverns depths.
Magma pools and gas vents and from hiding spot a salamander who snaps his fingers and a gargoyle bounds around the stone and bounds ahead. Further in is a squat structure of shiny obsidian built like a squat tower. The black structure rises only 30 or so fee up and has a lava stream flowing out of its base on one side
