Jace came to Innistrad after Ugin urged the Gatewatch to find Sorin. Instead of an ally, he found clues scattered through Markov Manor, the Drownyard and villages losing their grip on ordinary reality. The symptoms crossed species and institutions, which made a single criminal or local curse an increasingly weak explanation.
Avacyn and her angels had begun judging humanity as the corruption they were created to contain. Wards failed, cathars lost their moral centre and people who relied on the Church discovered that obedience no longer offered safety. The protector’s authority made her change more dangerous than any isolated monster.
The investigation forced Jace to work differently. Telepathy could expose a mind, but the mystery existed in architecture, tides, symbols and stories accumulated over generations. Tamiyo’s journal gave him another method: compare patterns, preserve contradictions and treat a world’s folklore as evidence rather than decoration.
