Apert

Apert is a significant recurring observance within the mathic world. When Apert arrives, the gates are opened under ancient rules: for ten days, avout are free to go out and visitors from extramuros are welcome to come in.

First appearance and context

Apert is referenced during preparations inside a Decenarian math, where work is accelerated to be finished beforehand and senior avout review conditions beyond the walls. On the eve of a new year of the Reconstitution, it is stated that both the Unarian Math and the Decenarian community will celebrate Apert together, with the gates opening for the ten‑day interval.

Cycles and participants

Different cohorts observe Apert on different cycles. In the current discussion, Unarians and Decenarians share the imminent observance, while the Centenarians are preparing for a rarer occurrence. The Centenarian Gate (see Centenarian Gate) is said to open on its schedule some years hence, and their community maintains extensive records to ready themselves for their own Apert.

Practices and preparations

Leading up to Apert, avout “bone up” by gathering information relevant to meeting extramuros visitors and to venturing outside. This includes structured questioning of artisans and other outsiders, and ensuring practical tasks inside the concent are completed ahead of the opening.

Significance so far

Within the narrative to date, Apert functions as a fixed deadline that shapes planning, maintenance, and outreach. Its defining features now known are the opening of the gates and the ten‑day window of reciprocal access.

Current status

Apert is imminent at the close of the current A.R. year for both Unarian and Decenarian communities, with a further opening anticipated later for the Centenarians.
