Giant of Titan
From Jenny Everywhere Wiki
The Giants of Titan roamed a normal-sized Earth in one universe. They physically looked just like human beings, simply scaled up to twenty times as high as trees.
After most of her incarnations died, Jenny Everywhere lost her connection to this universe, leaving her unable to contact Jakob, a particular Giant of Titan with whom she'd had a close relationship. (PROSE: Jenny Everywhere, Signing Off)
