Ereinion Gil-galad, son of Fingon and Elemmirë, former High King of the Noldor, half-brother of Ingil, Amarië, Ingwiel, Ariel, Canyafinwë and apparently another one? Father of Gwilwileth, best friend of Vëantur, ally of Elendil, nemesis of Sauron (yes, that's what we're calling it these days) and lover of Dior. That's quite enough to be going on with.
