The temple of Iomedae has services every morning. Blai isn't qualified to give them, because even if he were given a pre-written one from a book of some of the best Iomedaean sermons, he is not trained to the point where his agreement with the content is meaningful and he is even more not trained to the point that anyone could ask him for clarification afterwards and get it. But it's all the instruction he has right now so he attends them every single day.
This time, Ser Cansellarion is in attendance.
Blai knows he can teleport with those boots, but hopefully he isn't planning to do it right away after the sermon ends, because Blai really wants to talk to Ser Cansellarion, and he wants the boots to still have their charges, this evening.
