I adored Peacemakers from the start (thanks to friends recommending it to me), and it's still one of my favorites. During the most recent Yuletide exchange, I luckily had the chance to write a Peacemakers story (which of course meant I had to rewatch a bunch of episodes, oh darn :D ).

Where the marshal lives and works, there is an unfinished room.
Calibrating from other stories I saw listed here (like Arduinna's, and Keiko Kirin's), I'd say you'll find the slash element slight--I mean, it's a primary emotional underpinning, but the surface appearance is very subtle. For what that's worth.
