These spectral apparitions are shards of living essence that wander seamlessly between the worlds in the same fashion as parasites in a search of a host. The ordinary folk wrongly deem the Wraiths for being the ghosts of the departed.
While the forms in which they manifest in our world are often chosen arbitrarily, they always share the same traits - wicked cruelty and unquenchable hunger of mortal souls. These spiders are nothing more but the material form chosen for the demons unleashed by the curse that holds sway over Zagoravia. Those who are unaware of the true nature of demons could easily mistake the giant spiders infesting Zagoravia for beasts of the twisted wilderness.
