So, the first jump in the RP is the first jump our characters make? Or have they discovered that they have this ability before? I'm asking this mainly because I'm confused about power diversity in the group.

I GMd a multiverse-hopping RPG before and had it so that the first characters we had were making their first jump, so just starting out. Later on we'd bring in vets, people who were more experienced in jumping.
