Repanse never drank the Grail. You're assuming I'm talking about gods, except here's the thing.
I'm not. I don't think this spontaneous creation of artifacts or blessings is related to gods. I use "Divine Energy" in this case to refer to nascent belief, but I don't think that belief has to be attached to any god. A sword killing a Daemon might get enchanted properties as a result of the legend or deed built around it, but I don't think any god has to be involved in the process. Humans can believe something, and it can become true through belief, becasue the Warp works in that way. No gods necessary.
Also, funny detail. The Red Duke of Aquitaine's statblock in Night's Dark Masters states that he has the Virtue of Audacity and Virtue of Chivalry. Virtue of Audacity means that if his enemy has a higher strength score, he uses his enemy's strength (useless in most cases because he already has 75% strength). Virtue of Chivalry means he can call on the Lady's Blessing by spending a Fortune Point. The only thing stopping him is that he has no Fate Points. I also don't think any GM would use this oversight to give the Red Duke the Lady's Blessing.
