Assuming a disqualification for any original fiction setting and fudging rules on fusion’ed characters and textual ghosts:
- Faron – the Falathrim elf of Nargothrond and later long captive of Angband (Implied Faelindis as #1.5)
- Ravennë – High Queen of All Eldar, Queen of the Vanyar, Ingwë’s equal
- Bortë – First Queen of Númenor (cheating because it’s really the concept of her history and her immediate recent family generations)
- Ilsë – Admiral of Alqualondë (her mother Linkwinen almost wins this spot)
- Arodreth – I love all the ten OCs and backstories for Finrod and Beren’s companions, but old Arodreth was the first and best pathos. Another day I might say Fân or Heledir. Or Tacholdir the pin-maker. Change my answer! Tacholdir!
