In faction you can define "coexistence" parameter with other factions. Description is rather vague and you won't really understand what that parameters does. I also saw few mods trying to use it to "fix" mas wars in Shark or imprisonment of Shinoby Thieves in various towns, which are common problems players are encountering. Therefore I did some testing and the result I found is:

"coexistence" parameter prevents NPCs with "attack enemies and neutrals" AI goal from attacking neutral faction, if they have a coexistence set with it. It does not prevent fights in any other conditions I have tested. In other words it won't "fix" problems in Shark or problems with Shinoby.
