Bring the drop title, the chapter you think comes next, and whether you care about plot order or cover variants. If you are asking about ledger files, say whether you already keep a spreadsheet.
Hours for telephone calls are weekdays, late morning through early evening London time. Email is read on the same desk. We do not operate a ticket portal.
Do not send private keys, seed phrases, or export files that contain account credentials. A chronology question never needs those.
