An aranea is an intelligent, shapechanging spider with sorcerous powers. In its natural form, an aranea resembles a big spider, with a humpbacked body a little bigger than a human torso. It has fanged mandibles like a normal spider. Two small arms, each about 2 feet long, lie below the mandibles. Each arm has a hand with four many-jointed fingers and a double-jointed thumb. An aranea weighs about 150 pounds. The hump on its back houses its brain. Araneas speak Common and Sylvan.
