Staying on the sort-of-villain-but-not-really train. Here we have a sort of.. "bad ending" I guess, or like an Act 3 villain victory before the finale starts, ionno, world's your oyster. The Light part only works thanks to Themurloc's Templar Class vfx mod (https://www.xivmodarchive.com/modid/34660). Otherwise I'm pretty sure it'll show up as the normal Delirium darkness effect, I'm not sure on that, didn't test it.
