There's us, and then there's Lacerta, who are our partners. We're dark blue, they're dark green. If you can't find one of us, they're probably the ones to go to; they've got a couple of healers, and that's rare enough that they're pretty popular.
Next are Cepheus and Orion; dark purple and yellow. Orion's probably the strongest ally we have, and we're generally on good terms with Cepheus. Cepheus tend to be on good terms with everyone; Red's the one to go to if you have questions nobody else can answer, and Claude works the forge. We tend to work very well with Orion, and we try to get each others' backs when we can.
Pyxis and Cygnus are another pair we're on relatively good terms with. Pyxis has some issues with our partners, or did until recently, but they've been fine with us. They're fighters and brawlers, mostly. I used to know a lot of people on Cygnus, but most of them are gone now; they've all gotten their wishes and moved on. They're going to be getting enough new people that it could change how they react, in general, but there are still some good people around.
