Temple of the anvil:

In the most sacred of all the Dwarven temples they have a mighty anvil which used together with their smithing skills can create the most powerful weapons and armor.
The anvil is praised by the Dwarves and only the most skilled are given the privilege to use it. The Anvil is indestructible and it was found deep in the earth. No one knows who actually made it but it is believed to be a gift from the gods themselves and only the Dwarves have the skill and knowledge to tap into its vast powers. The anvil is named SoulSteel, aka the holy anvil or the anvil of sound, some even speculate that it is alive. Every time someone uses it a mighty song appears from the anvil and fills the halls and the better the smith is the louder the song becomes.
