For authors

Reach LitRPG readers and shape how your series appears

Claim your series

Claiming is free. It does not require a paid plan and does not automatically make the codex official. A free claim gives verified authors a route to request corrections, set image preferences, raise concerns, and request review or public delisting of unofficial codexes relating to their work.
