Nerezzar

Nerezzar, a necromantic god worshipped by some devas.

It's mentioned that Sikander fighting his nephew Nerezzar (during the Divine War?) destroyed the Elves' Flower of Life which turned the Elven Forest located in Arun into a lifeless wasteland. Same fight also opened the Great Rift.

This god is not mentioned in game. Lore about this god is from TERAHispano TERA Lore interview with En Masse writing team Marti McKenna. It's possible this was early name for Lakan.
