I should specify. Tristram is 0% interested in freedom as a virtue, and would never get an item hallowed to it. In fact, because he blames the heresy for the death of his family, he is probably even less interested than the average person in Anvil in getting involved with the heresy.
My idea is that recovering a shield (and maybe more) hallowed to the virtue would be a more fun way of introducing the item into the game than simply having the story, he went to the shield shop and bought it. Also it could have fun RP effects - and generate game by him getting it unhallowed (that’s a thing right?).
That being said, from a point of view of understanding his family, if the opportunity ever arose to meet with a devote of the virtue, he’d be interested in hearing about it, just to understand his family; and as for obvious reasons he is not in favor of killing freedom heretics, he would not hand them in.
[If anyone could put me in contact with a player that follows freedom, I’d love to have a conversation OC so we could create some shared backstory- perhaps they knew someone who might have known someone from Cairleon].
