The Codex is an in-game database containing data on all aspects of Warframe. Several sections of the Codex are automatically populated as more content is released (Warframes, Weapons, Events, Sentinels, Sentinel Weapons) and are additionally used to track player's progress in attaining and leveling those items.
In order to obtain information on enemies and objects for the Codex, players need to scan the relevant items using scanners. Codex section for Kuva Liches will be available after the player creates their first Lich.
Information for other categories is obtained by owning the item in question (Mods) or by progressing in Mastery Ranks (Art Gallery).
