Chamber 09 · Confiscation Vault
Unfilled Crypts
Tombs without occupants
Clear the previous chamber to unlock this one. You can still preview the briefing.
Briefing
Beneath the vault, some crypts were carved and never filled. The archivist wants every tomb listed — even empty ones — alongside any prisoner buried there, if one exists.
Objective
Return all tomb names and buried prisoner names (including empty tombs), ordered by tomb id.
Hint
LEFT JOIN keeps every row from the left table even when there is no match.
