The Alarast

A mysterious god-like being from another plane.  It is also known as "The Betrayer".  It has appeared on the material plane once so far.  It is known that Mokesh serves the Alarast, but its ultimate plans remain unknown.
==Description==
It appeared on The Isle of the Lost God as a huge male humanoid that appeared to be made of shifting, translucent black smoke filled with glittering lights filling a human-shaped glass form and clad in glowing gold armor that had panels of shimmering energy covering the gaps.  Its eyes were made of lightning and its gauntlets dripped electric-white sparks that brought order to the chaotic land they fell on.  A massive greatsword made of solid white light was worn on its back.  It would fade in and out of existence constantly, sometimes moving from place to place in the blink of an eye.
