**creature** is a tiny in‑memory key‑value store that namespaces every entry to a specific “creature” (user or character) and tracks what that creature has seen or remembered. It provides simple functions like `creature(id, name)`, `creature.see(id, key, value)` and `creature.remember(id, key)` and is designed for event‑sourced scenarios where each user’s memory can be logged, replayed, and merged across shards. The library is aimed at developers building virtual worlds, games, or any application that needs per‑user/session storage without a full database.
