Ungam

Ungam is the first golem with a soul. In mortality Ungam was a dwarf and a faithful of Seshet. The dwarf always competed for the attention and commendations of his master with more and more elaborate creations. In a final act to impress his master, Ungam stubbornly volunteered to inhabit a mechanical body of his own design, despite Seshet's warnings against it. The trial was successful, but Ungam's soul was rejecting his new body --- the process threatened to tear his soul asunder. In an act of compassion for his aspiring student, Seshet imbued his body with a piece of his own soul, ascending his student to divinity.

As a golem, Ungam had lost touch of his senses, but with his divinity came ambition and power. In his new body, he had nothing to distract him, so he did what he was good at: build. Ungam, for centuries, tinkered in the underground, creating vast improvements to technology and infrastructure, and when he got bored, he began building on himself.

Soon, Ungam was massive in size. On his own backside he created fortifications for a citadel, sprawling with factories and workshops. In this citadel, he began producing the first of the warforged --- golems with a touch of his own soul, to work in his citadel, producing and creating. He even offered any creature the opportunity to become a warforged, if they would trade their body for a mechanical one.

Soon Ungam's citadel would become so expansive it would rise out of the underground. He would send out his warforged onto the surface to build, and observe, and accumulate knowledge for Seshet's library. In the end, he still works to impress his master.
