I don’t really have that many, tbh Nonnie.
I think he was a lot warmer in his demeanour than our chilly diamond Thranduil. We know he was impatient – heck, that’s why he died at Dagorlad, through impatience. He didn’t wait for the signal.
I also think he had a real open dislike and resentment for the Noldor, heh. After the fall of Doriath, we know that the Sindar didn’t want to stay with Gil-galad and the rest of that lot, and instead they left the safety of Lindon and moved east. I suspect Oropher was all ‘fuck you, i’m out. Gonna be a king far far away from you crazy tragic murdering nutbags and your crazy world-destroying dramas.’
Basically, my mental picture is of an Elf who doesn’t have the icy demeanour, long-hidden wraths and griefs, and incredible ancient endurance of Thranduil. Instead, my Oropher was a quick-speaking, quick-thinking, witty and personable sort of Elf, with an almost-Manlike lack of patience, and TONS of Sindar pride. I suspect he was very well-liked, a very popular Elf. I mean, the Silvan Elves made him King, after all.
I bet he was a great dad.
