The Shields of Mikhail
Eivar is the god of the Forge and the Mountains. He is often depicted as a completely bald dwarf wearing a smith's apron striking a bar of red-hot metal with a hammer. Older depictions of him have him clad in full-plate armor and carrying a two-handed warhammer.
Originally Eivar was the god of War and Battle, but after the Ascencion he relinquished his duties as the god of battle to Mikhail, who led the attack against the Gnolls in the Gnoll Wars leading to the eventual defeat of Yuukar. Since then there hasn't been any large-scale conlficts after the Gnoll Wars, his role as a god of War has declined leaving him as the god of the Forge and Mountains.
Most smiths worship Eivar as their patron god, believing that he assists in every strike of the hammer on the anvil. There are some older dwarves whose parents fought in the war who worship his earlier role as the god of War and Battle, but they are rare.
