You have the ability to travel through the multiverse at your leisure. You can target any dimension you have already visited easily but accessing a precise destination blindly will require some practice, in the meantime you will jump to semi-random destinations every time. You can teleport to locations you are familiar with in the same dimension or one you have not visited provided you have the coordinates relative to yourself. However, teleporting inter-planetary distances require careful planning to hit your target.
Additionally, your body changed to accommodate cross-dimensional travel to become a projection of your soul. With time and study, you will be able to alter your appearance at will and even replicate the abilities of other creatures; this does include supernatural abilities like magic, psionics, or cultivation. However, while you are able to cast spells or use psychic techniques, you do not have the knowledge to do so. You can of course learn by yourself, at your own risk, find a mentor to tech you, or pick any of the powers available in this section.
In time, as you grow in power and familiarity with your abilities, you will be able to open portals between locations and even dimensions, create your own pocket spaces or even fully fledged demi-planes under your control. You can reach the power of Elder Worldwalker in around a decade of study, practice, and regular travel. The more time you dedicate yourself to it, the shorter this time becomes.
