An ancient mystical floating island discovered by AEGIS with the help of a mystic named Morgan in the Bermuda Triangle. After much negotiation with the local Council of Nine, a group of ageless sisters
1 whose connection to the Realm Beyond the Mist allows them to shift the island into the mystical realm, AEGIS managed to gain permission to build a military outpost on the island. At first this was merely a watch station with the duty of monitoring the mystical realms against incursions into the material realm, but slowly over time, with the backing of the Council of Nine, the base became AEGIS's centre of operations.
Protected by the semi-sentient Caliburn, a weapon system capable of bisecting every molecules in any target anywhere in its line of sight, the base houses the Forge of the Ancients, a nanotech facility capable of producing practically any piece of equipment the organisation could require, under the observing eye of Ironside, the Chief Forgemaster, a product of the Forge herself. Military control of the island is technically in the hands of the Council of Nine, however most day-to-day affairs are dealt with by their proxy Nickelback, a self-aware AI Construct created by the Forge to ward it from the growing tide of metahumans appearing in the world.
The island hovers above the ocean at a high of 2000 feet (600 metres) by means of a series of ancient lodestones located around the lower levels of the island, but is also locked in place by the stones, preventing the island from moving geographically. The stones do not seem to interfere with the island's ability to move dimensionally however, which allows the Council of Nine to transport the island to the Realm Beyond the Mist in times of danger. Or transport it back to the material world if under attack from the mystical one.
A sacred vault is located in the centre of the island, beneath the chambers of the Council of Nine, where a great treasure is said to be housed, and while the sisters spend most of their time within the vault when not in council they have swore not to speak of its contents until the time comes that the people of the land require it most.
