Used by Vamdemon in Digimon Adventure, it was where the Chosen Children's Digimon were created as Digitama with the help of Gennai and his kind. Piemon seized the castle with an army of Guardromon and Mekanorimon while attempting to destroy the Digitama, but Gennai was able to take the eggs and escape. The castle was relented to Vamdemon later. The castle sits atop a steep mountain and looks European in design, but seems to defy the laws of physics on the inside. Gravity seems to be undefined, and it is possible to walk on walls and ceilings, and the castle appears to be the merging point for multiple dimensions in time and space. Vamdemon used the castle as a training center for his invasion forces before they left for Earth. The castle also contains a large set of doors which act as a portal between the Digital World and multiple other dimensions, including Earth's. The doors are accessed by a keypad that uses Digimon cards placed in certain positions and in a certain order over the keypad to determine which dimension the door accesses. Vamdemon and his forces went through the doors to invade Earth, and the Chosen Children later followed.
