I've been doing some quick research into Psyonix - don't have a lot of time tonight - just spent an hour using my research techniques.
I have found this render on a portfolio site belonging to one of Psyonix's art staff
. I'm going to do something that I don't usually do - and decline to link to the site specifically - as I don't want to get the person who has uploaded it into trouble.
The image was displayed in a portfolio under the heading "vampire creature concept". Fans of the Legacy of Kain series will note that winged vampires are significantly important to the lore.
If (and I stress the if
) this is from War for Nosgoth - it could represent a few things - a devolved Razielim, a twisted Ancient, or even Janos Audron himself post-burning within the Demon Dimension.
