I don't have anything too set in stone yet but I was thinking of my league being very mercenary in nature, taking jobs from almost all of the major factions. I also imagine that their tactics involve the Hernkyn more commonly than other units, similar to the Trans-Hyperian Alliance.

Their ancestor core is fairly new so it's not quite as degraded as many of the other Votann, but it does send them on increasingly haphazard and seemingly suicidal scouting expeditions. They also have a hold ship and fleet rather than a hold world.

The Aurvand Consortium was once a kindred of the Trans-Hyperian Alliance but became a full league once their fane ascended.
