Where am I supposed to go after the Hollow Crow?

[BhaalSakh]

So I have just beaten the Hollow Crow boss and purified the beacon. There are two left, one of which I assume is still in the snowy area? Not far away from the beacon there was a large area where the dude on the dragon attacked me, but from there the only thing I can find is a shortcut that leads on the path near the start of the map. From the screenshots I have seen, there seems to be some kind of castle or abbey in the snowy area, but I can't find any way to get there? There's nothing on the online guides either.

The Abbey and castle are in other areas. The abbey holds 2 beacons, which adds up with what you are missing. The way there is via the Manse of the two brothers, which is accessed via an elevator in Pilgrim's Perch.

The Castle is the final area in the game and is accessed after all otehr areas are cleared through a small door in the area just before the Pitia boss fight.
