Astra Codex

Welcome to the Astra Codex, a worldbuilding archive for the shared universe of Ritual Division, Miracle Service Terminal, and related stories set on the planet Astra.

Astra is a post-cataclysm fantasy-science setting where magic is not merely myth or superstition, but a reality-altering phenomenon shaped by mana, machines, biology, history, and human survival. The world is still recovering from the Cataclysm that destroyed Meridia, now known as Demise, and forced civilization to rebuild across Mahanusa under the survivor nation of Indomitable.

This codex collects notes on the people, technologies, magical systems, institutions, and historical events that define Astra.

Ritual Division

Ritual Division follows the mecha witches and ritual machines who defend humanity from threats born from Demise and the Deep Unknown. Their world combines military science, magic thermodynamics, mana-powered technology, and the remnants of a civilization that once believed it understood reality.

For body limits, caster biology, and why people can survive magic at all, start with Mana-Adapted Physiology, Manavascular System, and Thermal Cycling Tolerance. For the human arms race around implants and elite training, see Artificial Manavascular System, Human Performance Enhancement, and Mana-Beast Materials.
