A newbie Systems guide to rebooting

Callyn had only just died and been re-born as a weird plant-based LitRPG System when calamity kicked her butt again and cast her away from the larger Mother System. Alone. Connected to nothing and no one. The one thing a System should never even be able to be. Now she's stranded on a rock free-floating through space. Eldritch-lite creatures stare at her hungrily from the void, and there's only so much oxygen left on her tiny world.  Fantastic.
