Yukon Hypogeum

The Yukon Hypogeum is a subterranean structure that is located in Hesperia at the border between the Republic of Alaska and the Republic of Quebec. The Yukon Hypogeum is one of the several hypogea scattered across the Earth, and the only one located outside of Europe and Asia. The structure was created by Élysabeth d'Athènes during her arrival in the New World as a base of operations, and through magic is linked to the other hypogea, allowing travel between structures.

The Hypogeum was undiscovered and unknown to the public prior to being found in 2018 by Hotaru Satou and Tritsya Kuroki while attempting to escape from a vampire in the outskirts of the Quebecois town of La Fleuve Blanche.
