Overview

A study, a circle of chalk, and eight Sigils that make each other. A deep incremental about tearing down what you built: six nested prestige layers, a Constellation you arrange by hand, time magic paid for in resets, and a story with an ending.
The house came with the study, and the study came with the circle.Your predecessor left no letter. There is a circle chalked on the floorboards that has not smudged in years, a stub of chalk on the desk, and a candle that has not gone out. Put a hand inside the line and the circle gives you mana.Buy it once. No ads, no...
