Full glossary
Every ESVA term in one single form, with the definition in use.
reviewed 8 August 2026
What it is
The glossary gathers the ESVA terms into a single form. It exists so that the same word means the same thing across the wiki and inside the game. The term is here; the live value of each table is in the game.
How I do it
Each entry carries the term and the definition in use.
- esvacreature that is measured, contained and registered; base unit of the game.
- deviationa reading outside the normal range in a quadrant; it announces an esva.
- containmentthe act of closing a measured esva into a flask; the result goes to the Register.
- bandthe grade band an esva falls into once measured.
- incursiona map region; there are 9 incursions.
- quadranta subdivision of an incursion where the deviation appears; there are 90 quadrants.
- Orderthe institution the player answers to; it issues mandates and Aval.
- Postthe player base; it gives access to the Register, the collection and the Market.
- collectionwhere every esva that is not in the party is kept.
- partythe 6 esvas that go into the field with the player.
- apparatusgear the esva carries; its effect falls into a capped category.
- flaskconsumable used to contain a measured esva.
- movethe esva combat action; each esva carries 4 moves.
- classthe esva family; there are 13 classes and each has its own drop row.
- Chainan unbroken run of registered actions; it breaks when the run is interrupted.
- Edge Casea species alone in its own family: it sits outside the Chain and does not advance along it; it is the only esva that ruptures.

- Rupturethe Edge Case's combat transformation: while the Rupture Reagent sits in the apparatus slot, it holds the ruptured form. No other esva takes it.

In development
What is missing: the values some terms point to — cap, odd, price — do not appear in the glossary.
What already holds: the term and the definition hold in the seven languages; the live value stays on the matching screen inside the game.
What I get — and what it costs

What it costs
