There are multiple species within the Faerie genus in the Steel Realms.
Long ago were the ancient Aelf names abandoned, though because of their long lives, some still persist… or echoes of them. The use of last names has never been of importance among the elves, most adopt of “of _X_”, where _X_ is the clan, Weald, of Soul Well they are closest bound to. All faeries follow the same conventions, regardless of sub species. Generally naming is universal for faeries across Helca, with nuances as normally provided for in Feyloise of the Steel Realms.
Although not known to the world outside the faerie kin of the Steel Realms, The faerie and specifically the Ilyndrian elves were transfixed with agony when the Altainen Rock Elves were nearly all killed in the Fall of the Grand Barony of Altair.
