Your Spark has ignited, one that the Pre-Mending Planeswalkers once held. You can planeswalk through the multiverse at your leisure. You can target any plane 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.
Your body is now a projection of your Soul, in time you will be able to alter your appearance at will and even replicate the abilities of other creatures. Your Soul is also a powerful source of Mana. While you are able to cast spells, you do not have the knowledge to do so.
In time, as you grow in power and familiarity with your abilities, you will be able to create your own pocket dimensions and planes.
