Sorry, didn't think to follow up here. Here you go:
Clan Motto: Aliit ori'shya tal'din.
“Family is more than Blood”
Clan War/Rallying Cry:
Nynir iviin’yc! "Strike fast!”
Clan Epsis adheres to a more modern secular Manda, though they retain some neo-crusader elements (such as some titles). They focus on the Resol’nare and keeping the culture preserved within their clan structure. Clan Epsis does not focus on the religious aspects, though that doesn’t mean none of them do. There may be a few amongst the ranks that have adopted the spiritual views as well.
Clan Epsis has a sorted reputation amongst many of the other clans, who might view them as more unrefined Mandalorians, or Mando’ade that follow the Resol’nare but little else. Many know their clan was split during the Crusader's Schism, which had severely dwindled their numbers. Clan Epsis is known and respected for being specialized in taking down Force attuned opponents. They are known to be less rowdy than other Mandalorias, perhaps also giving other clans the notion that they think they are better than other clans, though in actuality, that might not necessarily be true.
Any clan that was stuck on the defensive With Mand'alor the Avenger in the Core Worlds would have fought alongside them. It's also why the galaxy hasn't really heard of the clan's exploits in a while.
