That's a point actually. The derogatory nickname for the Aldmeri Dominion in the PGE1 is Old Mary Dominion. So Aldmeris=pronounced Old Marys?
I think the PGE is more playing on the idea that ald=old, while simutaniously mocking the mer by calling them mary's, a traditional schoolyard insult, infering 'pansy' or 'wimp' while also being a clever play on the word Mer, pluralized.
I didn't mean to have a point, just having fun in the same theme as the PGE.
