So from what I read off the wiki they are led by sorcerers who also use large numbers of mortal followers. Sorcerer led makes me think the 4th at first. However large quantities of mortal followers makes me think back to Darktide and that feels like the 1st company a bit with the number of poxwalkers.

Is there any definite proof for one or another or at least strong speculation?

Thanks for the help in advance brothers.
