The Fortress of One is a Siderealm contained within a single round tower, perfect in shape, with a myriad of floors and chambers – all perfect in proportion and size. The dwellers of this fortress are many, though said to all be manifestations of a single entity. Time has no meaning in the fortress, and the vision of The One is said to stretch from the start of time until the end. Few beings are capable of grasping the perfection of The One, and having their minds not be blasted when exposed to its mind and presence. It is said that The One is so perfect, that it can only be contained by the perfection of the fortress.
