Let's make something clear. I got where I am in this world by being ruthless in a particular way. I make deals and I keep them, and I break those who would break them.
Ruthless mining magnate and banker. Likely one of the richest people in Erenen, and scion of Clan Orim.
His Tedonth Ath corporation runs multiple mining operations throughout the country. His bank and the security it provides have become a highly profitable venture on their own.
Rumor has it, not just through dwarven techniques: also through strong-arming and dirty, dirty tricks.
Needed a place to stash his loot; decided to start a banking business while he was at it.
Found The Bastion, right here in Heaton. Built brick by brick from imported stone from Eimrar.
During the Heaton Heist, Umbrun personally killed Gimlen and Boltu.
On the 18th of Midsummer, 642 5e, the Granite Lord made her move against Umbrun, following a long-lingering underground war between Umbrun's Tedonth Ath and the Granite Lord's forces.
Umbrun foresaw this attempt and used the opportunity to empty out The Bastion, escaping with an unknown amount of funds. He left a stone statue of his likeness, framing Glonora for his murder and faking his death.
His current whereabouts are unknown.
