Powers
By touching a flat surface, like a wall or the ground, Knov can set and open a portal leading to an artificial dimension — a four level mansion containing twenty-one rooms of various sizes. Each portal is linked to a specific room, with the maximum number of entrances being dependent on the size of the room, with each room being completely separate from the others. Normally each entrance can only lead back to the portal Knov created for it, however, Knov can use a master key to connect any room exit to any previously set portal. When not in active use by Knov, the portals are closed and impossible to detect.
