What factions are there in EVE that you can run agent missions for that either don't lose you faction with the four major nations, or at least bring up such missions infrequently?
Since I last played CONCORD and Jove have had their agents taken off the grid.
To my knowledge, Servant Sisters of EVE is the only one left (and all their combat mission agents I know of have been turned into distro agents) but I'm curious if there are others.
Please indicate what security region (high, low, null) the agents occur in.
