Pylia extended her lantern over the edge to get a better look at what you were talking about. However she shook her head. "Sorry, but I've never seen one of these before! It must be some sort of spirit, has it tried saying anything to you?" Shortfang was just quiet and continued to look, ready to fight at a moment's notice. As for you, as far as you know the crab is simply defending itself from you, as you've gotten too close for it's comfort. But the spirit was hard to read. It didn't help it's face, or whatever it was, didn't really show any expression and it's body language was fairly neutral (sitting on a crab). It did look down at the gemstone eye then look back at you. "Maybe you need to trade something? If this spirit is fey, that's how they usually operate. An item for an item of equal value."
