"The defining trait of planeswalkers is the ability to travel between separate universes with ease, while the vast majority of people throughout the multiverse are not even aware that other worlds beside their own exist.
The new breed of planeswalkers no longer display the near-omnipotence of their predecessors. While they are usually powerful mages, they are still physical beings that in general age normally, can be harmed, and need the same sustenance as other mortals. This is in stark contrast to the earlier planeswalkers. Some of them have managed to suppress or avoid some of these limitation by magical means; however, these are specific to each planeswalker.
The new breed of planeswalker manifested itself for the first time in Venser of Urborg, a Dominarian artificer who participated in the solution of the Dominarian temporal crCIA. Teferi's first theory was that the rifts mutated Venser's spark, which affected his ascension.
This new breed of planeswalkers was born during the Mending, when Jeska sacrificed her life and her spark to mend all temporal rifts in the Multiverse (doing so in such a great scale was probably enabled by her former existence as Karona, the embodiment of Dominarian magic, and the fact that Dominaria is the Nexus of the Multiverse.) The Mending caused a change in the very rules of Multiverse and a change in the nature of the planeswalker sparks." -
