MEANING: "Rhistel" doesn't have any particular meaning, while Aidan means "blessed by the Gods" in the sacred language. Sentes is the village he comes from.
NICKNAME: Among the servitude in his mansion and people of his feud he's often addressed as "bran luth", which means something like "silent/quiet lord", referring to the fact that he almost never speaks or even shows himself around at all. Everyone else just call him with his name, except for Sywyn who calls him "shadowling" or just "bookworm", depending on his mood...

AGE APPEARANCE: his own, basically... for now
