they probably have no idea who Thor is, Girard reffered to Soons god as a petting zoo so he didnt care about them at all so its possible they ahve no idea what the names of the gods actually are, living in the desert the only thing they were probably taught is the importance of family, how everyone outside the family is out to get them, how to cast illusions and how evil paladins really are perhaps when they see a LG cleric casting ressurection even if the name of the Deity is Thor i dont think they get the Deitys allignment at all and theyd think "Thor" is one of the 12 gods
it makes sense for tha torder to happen, they were probably labelled based on the actual location of the gates that got translated onto the circle or perhaps based on which ones were close to each other for more info so since lirians gate is near dorukons gate theyd be next to each other on the pie chart and the one above lirians gate is the next closest so it makes snse for any enemy to unknowingly follow the circle around since theyd go after the closest gate especially if they realised that all of themw ere warned when one falls so the enemy would ahve to attack the gates "in order" essentially to be effecientThe monitoring magic item wasn't built with the intention to prophetize in which order the Gates would have been destroyed, and the fact that the light indicating the 3 Gates already destroyed are adjacent to each other is a mere coincidence (not even a terribly unlikely one, at that).
