Hello,
As far as I know, Faction in EQ is relative to "Person vs Environment" on all regular servers, and the progression servers.....Zek(PVP) and FV(roleplaying) I am not sure of though.
You could r.click on an NPC (of the faction you want) to measure from a safe distance (uninvised) and a message re your faction with the NPC would be displayed in your chat window.
Your faction indication in the message (after r clicking on the relevant npc) would be, from worse to best:
Scowling (or scowls at you) .....Threatening.........Dubious.........Apprehensive...Indifferent....Amiably.....Kindly...........Warmly...........Ally.
There is a feature in the Character/Achievements window but I am not sure if specific factions are listed there.
Hope this helps.
