As far as I know, it doesn't mean anything. Awen is a Welsh word for something roughly equivalent to Muse-like inspiration. I'm not aware of there being a plural and I don't know of any context in which a plural would be appropriate. KiNo thinks using it serves as druid credentials, just as he thinks using an online translator to generate pseudo-Japanese makes him a buddhist. He is a creature so devoid of anything even vaguely resembling a personality he will latch onto anything he thinks will lend him one.
The quest for Awen is a quest for the spirit of Druidry itself, and, as such, it brings together many paths. We may pursue the quest as historian, linguist, poet, philosopher, priest, magician, shaman, and in many other guises. Each, in its own way, helps us to gain understanding and, as we walk the Druid path, one of the things we discover is that in understanding lies strength.
The first recorded reference to Awen occurs in Nennius' Historia Brittonum, a Latin text of circa 796 CE, based on earlier writings by the Welsh monk, Gildas. Referring to King Ida of Northumbria, who reigned from 547 to 559.
