The faction for all unicorns was fixed some time ago since they were all threatening before. Black unicorns should be on Lithiniath while white unicorns are on Gelistial. At the time I did not try hailing her because she was threatening, so I couldn't tell if she had quest text.
Lady Gelistial does not have any quest text on p99 for some reason - Definitely something that should be fixed. Otherwise the quest and all its turn-ins work.
You have to get to Plane of Mischief (a pain in the butt, get yourself up there first before trying to figure out spawn timers) and then hang out for two different 16 hour spawn windows to finish this quest. The unicorns are killed very regularly on p99 due to their chance of dropping the higher tier cards for PoM quests. You can't solo them, so make your friends come to PoM too...
