Harmonia's necklace

Harmonia's necklace is seen as a hoodie and a hunky heirloom with two snakes entangled in an embrace around a gem stone.

Robin, a daughter of a nymph and son of Nemesis, found safety in Safe Haven after mortals and monsters alike threatened her life continuously because of her inherited heirloom, Harmonia's necklace. No one believed her when she foretold the future of an attack from a new enemy, Lin, Safe Haven has never seen before. The necklace is not seen again after Robin departs from Safe Haven.

The necklace is seen again in the weaponry black market, which could indicate Robin's death.
