After the encounter with the merchant who peddles what he calls quest items where their quests are unresolved and are searching for the right person for the job, Jaeden quickly had taken the crystal container that supposedly held the fingerbone of Saint Arabella,a name he recognized. It was the name of the founder of an order of nuns in the Dark Lands, where she had a reasonable following. If this was her finger bone, it would be a holy relic the church would be happy to retrieve.
Though he had no way to verify that the item was as claimed, and there had been no feeling of holiness when he had touched the container he never the less would hold it reverently as he took it inside the church. Going to the office of the highest priest he had reasonable access too. To present the item and telling the story that had been passed onto him from the merchant. The the last living member of an adventuring group had still had it among his articles and was unable to continue the quest. So the merchant had retrieved it, and it came to his hands by that merchant. He gave the name of the saint that the finger bone was supposed to belong to and then let the priest do as he would with such a curious discovery.
