[name_m]Aurelian[/name_m] is distinctive, golden, and poetic - it reminds me of gemstones, gold leaf, honey, [name_m]Saturn[/name_m], and autumn at the same time. Aw-REE-lee-en is nice - mystical, magical, like a spell. I also like aw-REH-lee-en for a slightly warmer feeling sound!
I personally prefer [name_m]Aurelian[/name_m] as [name_m]Aurelien[/name_m] reminds me a teeny bit of Alien
