If we're going by Presences that make little sense to anyone but ourselves...
Eomer's got a... tartan... presence. Hahahaha.... Please don't ask me to explain it. But
Eomer's image in my mind, regardless of me having a decent idea of what he actually looks like (see back pages), is that of Karl Urban in a red and black kilt.
Elennar is more like a wisp of cloud. A friendly wisp of cloud mind you, but a wisp none the less.
Morai has the essence of a long past time in my head. Crimson corsets and black gowns. Full length gloves, operas, and a tumble of dark curls.
The Barrow-Wight is a two-dimensional little green penguin.
Actually, when I think "BW", I think of a strain of piano music from
A Distance There Is by Theatre of Tragedy.
Gil-galad is Strong Bad (sorry Trogdor...).
