There's also Sirens, which are global moderators and being supportive to the God and Goddesses. (They're all female)
There's the God and the Goddesses, who are the forum admins.
In some places you might notice a GM, which is a moderator to that specific board, but is just a regular Lord/Lady/Knight/Dame besides that.
Unapproved, as you should know since you once held that rank, are people that just arrived on the forum and aren't approved yet, possibly never will be.
There are some more, less friendly ranks to have. If I recall correctly, those are all listed here: http://elliquiy.com/forums/index.php?topic=14105.0
