Zero
From ErfWiki
Zero is a conceptual place used in the understanding of MathamancyIPTSF Text 1.
Proposed Canon
Zero is considered a flat plane, in which all existence is a disturbance. These disturbances are known to Thinkamancy as G-Strings. The existence of a Unit is considered to Mathamancers as a debt, that would be repaid, eventually, by the croaking of that unit.
