As the head of House Jacos, Jared was the governor of the Aderonack region. After his only two children were killed in the Lakelander War, Jared lost the will to live, wasting away in grief.
Around 293 NE, Harrus Jacos replaced his brother more and more in administrative meetings, due to Jared being unwell for years. He eventually died and received two funerals, one at court in Archeon and one a week after in the Aderonack estate. His remaining family attended both funerals, among them his cousin Jessamine Jacos, both his nephew and niece, Julian and Coriane Jacos, and Harrus, who showed true pain for his brother's death. Jared joined the family tomb, resting in a marble sepulcher paid by Jessamine, who sold an emerald from her cane to a gem merchant in East Archeon.
The absence of heirs consequently meant that Jared's titles were passed to Harrus upon his death.
As a member of House Jacos, Jared was a singer, meaning he could use his voice to control people as long as direct eye contact was established
