Iothera (series)
From Jenny Everywhere Wiki
Iothera was a science-fantasy webcomic created by Nora Riley.
The comic took place in a science-fantasy universe with a planet Iothera taking the place of Earth.
Paul Hoppe, a fan of the comic, created several pieces of fan-art for it, including a one-page comic, COMIC: Jenny Everywhere And Iothera, which gave a glimpse of an adventure where Jenny Everywhere visited the Iothera universe and met the two main characters, Cassie and Maureen.
