Inkallu

The Inkallu are just those sensitive to the Inkallu . There are several different INkallu societies, each with their own philosophies and ways of channeling Kali Energy , and near all of them take on a religious aspect.
Inkallu tend to live 50-100 years longer than their species average. It depends on how powerful they are and how much their usage of Kali Energy has corrupted and eroded them. The most powerful live on for centuries.
The Word itself can be used as an adjective, indicating sensitivity to Kali Energy /Inkallu, or as a noun.
