Uerguin

He is the god of Autumn, Mining, and Stonework.  He is also the father diety of Dwarves, Gnomes, and Halflings.
During the final days of the 100 Years of Pain, hemanifested on Adonnance to bring an end to the age of the Dark One.

When his lover Y'veliet Rae was devoured, he became so distraught, he slammed his fist up the gorund before him, and created a giant crater. Upon the second strike, he shattered the earth below himself and the dark one, and sent shockwaves from a thousand miles. Much of the land within that area was left so unstable, that it crumbled and fell into the seas around it.

Uerguin and the Dark One sank into a deep void withing the middle of the crater. With the death of Y'veliet Rae, goddess of the spring, a deep and unnatural cold covered the area, sealing Uerguin and the Dark One into an icy slumber.

The Icon of Uerguin
Uerguin followers use an icon which is a golden axe head turned into an oak tree. Falling from either side of it's branches ia an acorn, a source of nutrition and symbol of understanding.

For his clerics, many of whom have a tie to mining and crafting, it is common practice to craft this icon themselves.
