Keltham is in fact on his way back!
With a brief stop at Maillol's office to check if anyone had comments on his informal proposal for an interim contract between Cheliax and Project Lawful (yes, in this folder), and any comments they might have on his articles of incorporation for Project Lawful (a smaller folder).
He also queried Maillol tentatively about the all-in costs if Keltham wanted to straight-up employ Yaisa himself while having her retain living quarters on Project Lawful, and to give Maillol early warning on that possibility / request that things should be configured now to allow that later if Keltham wants. Not that their relationship advanced anything like that far, or that Yaisa has even indicated any such interest, Keltham just prefers to keep that option open for later.
