On Judgement Day, a blood servant is executed by the elders for possessing a forbidden relic and questioning pureblood origins. Archivist Veyra is ordered to merely record, but becomes fixated on the relic—a tattered book Soren warns holds dangerous words. While registering the artifact as 'Origin Contamination', Veyra deciphers that the servant was killed not for the book itself, but for where she found it. Defying Soren's strict ban, Veyra uses the cover of scouting beast activity to secretly investigate the forbidden origin archives, setting herself on a dangerous path.
