Siphon

Siphon was an underground metropolis founded in the ruins of the Dwarven city of Kuzhalakan. It is the capital of Siphonea and the ruling city of the Mountain Tribe. The city was founded by Orkenspade the Great in 1203 C.E. and has been the home of House Sopho for hundreds of years. It houses 400,000 members of the Mountain Tribe. It was designed skillfully to resist any attack by the miners and builders that the Tribe was known so well for. It is said to have multiple hidden chambers of gold and jewelery which had been hoarded by the monarchs over centuries, but no such chambers have been found.
