The kulshedra is the mother of all ershaj and bolla. When the kulshedra dies the bolla return to the nest and begin a savage ritual in which they vie for leadership in a fight to the death. The fighting may go on for weeks until the bolla submit to a new leader. When this happens, the victor begins gorging itself on the corpses of the dead while the others return to their usual activities. Over time the new bolla queen will grow and undergo a metamorphosis which transforms it into the giant kulshedra. The kulshedra retains the bolla's venom, while gaining the ability to spit this venom as well as gaining full eyesight. It spends most of its life underground in its nest, eating food brought to it by the bolla and mating with the ershaj. If the nest is threatened however, by a nearby human settlement for example, it may venture out to the doom of everything it perceives as a threat.
