The Path of the Righteous

The Mace of the Crusader is extremely easy to recover if the player has sequenced the collection of the Artifacts right. The protagonist is supposed to travel to the Chapel in Cheydinhal and pray at the tomb of one of the Knights there. Then, they must "Follow their faith". Or, if the player already has the Boots of the Crusader, the task becomes much easier, as a path is revealed for you. Without wearing the boots, it is impossible to walk through from the door to the pedestal where the mace is placed (it is separated by a great nothingness), while with the boots, a path of light is laid in front of you. This is explained in a journal entry that says that the Boots have some kind of bond with the mace, and have thus revealed a path.

Once the protagonist returns to the Chapel, the servants of Umaril, the Auroreans, have attacked. The chapel is in an upheaval, but unlike Anvil's chapel, not all of the attendants are dead yet. They are fighting back, including their beefed-up security system, which just consists of a warrior in heavy armor.

Once all the Auroreans are dead, the soldier will express his relief and come to join your cause.
