The strange creature trails blood into the ice caves you were just in earlier. A manhunt is underway. You aren't sure how many of these strange creatures there are, but you're pretty sure that packing an extra blaster wasn't a bad idea.
Deep, deep in the ice moon is a molten core that heats even the caves, and keeps the plants alive. Deep, deep within the moon, ice hovers impossibly over lakes of lava and fire. Your scanners are picking up life forms somewhere down here.
