Lost Among Realms (w|w cast version)

1 argument, 1 inter-dimensional portal sucking in the 6 main characters, and 1 enemy within the various dimensions travelled. I'm kidding. There's more than 1.

This is (or should be) the mostly women main cast version. There's also a mostly men main cast version.

Throughout this series, six characters develop their powers and their relationships with friends, with siblings and with romantic and sexual partners.
They travel through time and to alternate dimensions both by accident due to a lack of control over their powers and intentionally due to being summoned to help save their world or a time line.
The series is light and the individual novellas can be read on their own in terms of the story itself. I try to recap any important relationship stuff that isn't clear and anything relating to previous novellas (I may have missed 1 or 2 things but I tried).
