Xisenin has invented many things. Here, they are listed. As time progresses this list will get larger.
Picture Portals/ Portal PaintEdit
PIcture Portals are special pictures made with Portal Paint, which contain secret ingredients that only Xisenin knows. When anything comes into contact with the picture, it will take the thing/things to the place it portrays. It is possible to make a Picture Portal to an unreal place, existing in the imagination, and in doing so, it becomes real. Xisenin keeps this paint in a secure, locked place, and, for good measure, it has no door at all, and can only be entered by teleportation.
