If I remember right, the Steel Wolves, when they split, went a bunch of a different ways. Almost two Clusters went with the new Galaxy Commander Fetladral to go back after Tigress, which after his dishonorable conduct against Anastasia Kerensky, was then taken over by Verena Wolf, the aerospace Star Captain (Now Galaxy Commander) all the way back from a Call to Arms.
The Wolf Hunters, about a battalion/cluster in size, went with Anastasia Kerensky and did their thing.
A smaller, couple of trinaries or binaries worth of vehicles (A Battalion maybe?) went with Xera Wolf and became the Steel Wolf Corps, an all-vehicle Mercenary command. Those are the ones in the Field Manual, right next to the Clan Protectorate.
Two Binaries joined up with an independent mercenary command that was last seen in Prefecture 9, scouting for lost Word of Blake Cells. That included a star of mechs, a star of Elementals, some vehicles, and a point or two of unarmored infantry.
And then there were the random star or individual warrior who just dispersed when Anastasia drank her 'merc aid'. Yulri Wolf was one of these. Same with Kris Carns, and Gwen Fletladral. Really interested to see what happens with Gwen actually, since the TRO mentioned she was nursing a serious hatred of Kerensky since he killed Kal Radick and ran the Steel Wolves into the ground.
I wonder if the Steel Wolves Corp could be lured to the Clan Protectorate. Start their own enclave there, reimmerse themselves into the Clan way of life. Most of them were probably Freeborn warriors from the Wolf Lancers Cluster originally though, so maybe they're happy merc'ing it up too.
