Some old EC names:
Pen'Guin - first ruler of Sirion
Saldor - first ruler of Omsk
Hydormie (I think...) - second ruler of Itorunt (Ryndhal being the first)
Emmanuel - creator of the Triumvirate religion, and former ruler of Itorunt
Zakath - possibly first ruler of Perdan... One of first characters in game anyway.
From Colonies:
Moira
Angus
Despyria (though that might be a bit controversial...)
Mortimer (a regular NPC for many years)
Dethargos
Broken
Valast
More to be added if I can remember any more from that far back. I have a few on the tip of my tongue that aren't quite appearing...
