The Tik Taan is a deadly mist which lies in an apparently bottomless pit known as the Chasm of Screams in the city of Usaro in the Mwangi Expanse. The Angazhan-worshipping denizens of Usaro regularly throw prisoners into the pit in the hope of keeping the Tik Taan sated – but it still sometimes rises up from the pit and flows through the city in search of victims. The (now extinct) Jambala Jaeg tribe fiercely opposed the cultists, and their shamans created ritual knives of bone and obsidian slay the demonic spirits residing in the Tik Taan.
