I don't see a problem with glamour here: use this word as a verb is definitively archaic, but the noun is still used widely today. While that modern usage is around, it is by no means the only one (in English at least), and it is not really a new meaning per se.
Dominions is not the first game to use glamour in this meaning either: at least a few fantasy roleplaying games (pen and paper) use the word in relation with Fey beings (and assorted creatures). And glamour is a much more common word in "plain" English than D&D cantrips.
