Rhagodessa are monstrous versions of a spider like predator related distantly to both spiders and scorpions. They resemble a spider superficially, but are longer, and possess an extra set of legs. Their front pair of legs act as antennae, probing the air and ground, while their back three pairs of legs propel them forward extremely quickly, gives them the additional name of “wind spiders”. They also have a pair of pedipalps, long legs which have an adhesive disk on the end, allowing them to grasp prey and bring it to their mandibles, which then crush the victim into jelly and suck the juices out. They can also use their pedipalps to climb like a regular spider. Rhagodessa possess no poison sac. They produce a hissing noise from their abdomens when agitated.
Rhagodessa tend to prefer hot arid climates, and are usually nocturnal hunters, although they are also seen during the day. Most are vibrantly coloured in red, yellow, or gold hues, to help blend into the background. Some also live underground, these are usually black or translucent, and make better use of vertical surfaces in their hunting.
