Observe
Choose a quadrant and read its incidence, materials and confirmed records.
ESVA is a browser-based idle creature collector about documenting an invasion. The world works while you are away; every important calculation is public.



A secret academic society studied impossible reports until observation widened a Breach that had always been ajar. The exceptions that crossed it do not degrade here; the world degrades around them. The Order measures, contains and publishes because secrecy caused the disaster.
Active play improves decisions. Absence never deletes progress.
Choose a quadrant and read its incidence, materials and confirmed records.
Your six-esva field bag resolves four active moves under a public scheduler.
One calibrated flask, one attempt. Success becomes a specimen; failure becomes evidence.
The Registry records confirmations, deviations, refutations and who proved an existence first.
Permanent, bound to your history, never a deviation. Choose a field method—not a difficulty setting.
The interface and the fiction describe the same work.
Effective incidence, containment margin, expected cost and observed versus expected results.
A rule grows stranger instead of a creature merely growing bigger.
Player value moves through escrow, ledgered trades and visible taxes. RMT is not prohibited; external trades remain at the players’ risk.
Mining, foraging, fishing, cultivation, archaeology and crafting feed a persistent economy.
Index, Vigil and Root argue over interpretation; guilds organize cooperation without locking content.
Every content wave leaks one coherent law, palette, material language and geography.
Odds, versioned rules, expected versus observed data and VIP/non-VIP samples belong to the product. Fiction admits uncertainty; the server does not hide arithmetic.
Public math, provisional science →Dates are targets, not promises. Every item moves through planned → in production → testable → released.
120 original species, the complete core loop, Field Notebook, economy, Market and real telemetry.
300 original species, the first three authored incursions, professions, clans, guilds and persistent progression.
Endgame submission, public records, achievements, rankings and server-first confirmations.
A recurring server event around an existence the Order has not yet confirmed.
Asynchronous competition with borrowed rarity budgets; collection is never nerfed.
Parties of two or three, instanced rewards and Excedente pursuit.
An active run format with temporary power and a separate risk curve.
A scheduled weekly encounter shared asynchronously by the server.
A new law, material language and roster. Theme revealed only after visual lock.
Long-term cadence without deleting collection, lineage or player history.
