Sal Vidon.jpg Not part of Riordanverse

The following article/section is from the Sal & Gabi continuity under Rick Riordan Presents and not the Riordanverse canon.

For five years, Sal has been able to peer into the multiverse. Sometimes he's even reached into other universes and brought other Floramaria's here. […] But now, thanks to this baby, he can’t do that anymore. It’s natural that he would feel disoriented at first. Of course his world seems smaller. But that’s good. That’s how the rest of us feel! None of us can kidnap people from other universes.
