He was born in the colony on the planet of Tau Cygna V, a descendant of the original settlers who arrived on the SS Artemis. Like all the other colonists, he was immune to the effects of hyperonic radiation.
He was a close friend of Kentor.
In 2366, when Lieutenant Commander Data arrived to arrange the evacuation of the colony due to the demands of the Sheliak, Haritath was the first to greet him. He was convinced along with Kentor of the need to evacuate, but did not say so openly until the colony's leader, Gosheven, was himself convinced.
