Val Hall is the stronghold of a Valkyrie Coven. It is in New Orleans, Louisiana and one of two covens in America. There are twelve worldwide including one in New Zealand.
Many of the members of the New Orleans Coven were members of a Russian Coven over 70 years ago, before Emmaline Troy's birth prompted them to move away from the Vampires whose Royal seat Helvita is also in Russia. It is unclear whether there is still a Russian Coven or if all the Russian Valkyries moved to New Orleans together.
The name of the stronghold Val Hall is a play on Valhalla, the god plane where the Valkyrie's god parents, Freya and Wóden live. The building is protect by Wraiths.
