It's the standard quest reward. Probably unintended, like the quests that give a Nikulas' Heavy Armor or an Essence Thief item. I believe there was another one that gives a set item from a different zone. One of them even is a level 50 (no CP!) item.
We reported this when the zone had just launched and Kevin confirmed that it was not in fact a bug. So these weird non-zone quest rewards are actually working as intended.
PC NA, CP2500+. Character creation is the true endgame.
