The quests in your characters' quest logs, each with its page on this wiki and the step you are on, worked out from what the game server has saved for your character. Sign in with your Yanis account; the wiki only gets to look, and your password stays on the Yanis website.
Quest progress is read from what the server saves: each character every few minutes, and at once when you log out or your quest log changes. Steps the server keeps nothing for are shown as “can’t tell” on the quest pages, where you can tick them yourself.
