Jace comes to Innistrad looking for Sorin, hoping to understand what remains unresolved after Zendikar. Liliana warns him that ancient power will not become cooperative merely because he has questions. She demonstrates how poorly his illusions fare against undead servants, then gives him shelter for the night. Her warning is practical, even when their personal history makes it difficult to hear.
Markov Manor offers no straightforward interview. Vampires and the human scholar Jenrik are trapped in its broken architecture, while psychic residue entangles Jace's memories with those of the dead. He must distinguish evidence from sensations that feel as if they belong to him.
Jenrik holds Tamiyo's journal. It identifies Avacyn as Sorin's creation, intended to keep vampires from exhausting the human population, and examines the strange cryptoliths. Jace leaves with a useful lead, not a solved case. The stones redirect mana; the angels are attacking humans; someone has devastated Sorin's ancestral home. Those observations fit several explanations. A clever investigator can mistake the first coherent explanation for the true one.
