Atreus was there - while he left early on Saturday and didn't stay the full time, he's in pretty good standing with Geliara and would've shown some illusion and protection runic magic off - he doesn't ask for anything in return! He always brings some kind of gift of an enchanted rune.
On Saturday he had Lore with him and on Sunday he had the foxes, who were very well behaved during the entire ceremony and only tried to sit in one witch's lap. Probably.
