Cathedral
Recorded per phase, because it differs per phase.
By day
Simply walk in. The cathedral is open to all, and while Coen is not yet wanted by the regime he does not stand out from the congregation — the walkthrough enters twice without incident. What the day gives is people: the deacon, the almshouse residents and Father Floren are all here to be talked to, and hex magic works, which the night does not allow. What it withholds is height. The scaffolds are out of human reach.
By night
Closed, with the entrance gate well guarded — and largely irrelevant, because the vampire does not use the gate. Plane Shift and Shadowstep carry Coen over the roofs, along the scaffolding and down into the walled courtyards, reaching the upper frescoes and the library balcony that daylight cannot. The grounds are patrolled and the guards are hostile to anyone found lurking, so the night route trades conversation for access and a fight.
Relationships public material establishes, in the absence of map coordinates.
The interior detail is from a developer-narrated walkthrough of a pre-beta build, played twice through the same quest. Layout may still move.
