- Lufkit "Merc Hall"

- Possibly a Merc Hiring Hall on Surebleak ??
- Or was Commander Relgen of Relgen's Raiders coincidentally on planet that day, to interview the Pathfinders??
- Some merc soldiers are retiring to Surebleak to provide security at the port:
"What was strange was the number of 'Bleakers who came home after they'd got done in the merc, which Miri had always sworn she wouldn't do -- and look how good that'd worked."
- “And in the meantime,” the Judge said, jovially, “it’s not like you don’t have protection. There’s enough mercs on this planet to start a war. Or end one.”
- Retired merc commander Angela "Liz" Lizardi is Chief of Port Security: Port Security Chief Liz Lizardi considered the man in the orange coat as one might consider an insect found in a half-eaten ration bar. “I might not arrest a man for having a joke. But I do—and I require my security officers to—arrest people who are inciting to riot”
- There might be a Hiring Hall on Surebleak, given how quickly the Pathfinders connected with Commander Relgin
