While skimming through the PDF for the first book, my distracted mind latched onto the analogy of boons as magic items that can't be transferred. Which made me wonder about while it's normally impossible, how would would you if you had to. This neatly leads to the second book and the concept of rituals. Now as absurd as it was to consider it might be worth developing. A healthy example of this might be the rites of inheritance for a barbarian tribe where the last chief is laid to rest and their heir assumes their role by inheriting the tribes power. A more evil version would be villains (or villainous PCs) hunting people who have earned a boon and plundering it. It could even be the same ritual, just a twisted version of it. Anyways not sure if the idea is worth developing but I thought I'd share it.
