The event had purpose as you both find the following has happened. As Antonis explains to you via telepathy, remapping of your mind requires remapping through an event that would impact you deeply. I am sorry for the shock but if you look in your minds you will find something altered something changed. For Elly she has several memories of her mother in her life returned to her. She now recalls that which Oslo and Emerald have tried to bury, her Father, a half elf ranger that in order to escape the wrath of Ember entered the mirror that they were told about by Antonis she also gains 2 wisdom. For Trelic the tragic memory of Betsy remains but it morphs every so slightly into a recurring source of inspiration where it once crippled him he can now call upon the memory once per 2 long rests to gain inspiration. His fear of water has subsided, and he gains 1 point of charisma as he now carries himself with a greater barring. The memories of the false tryst remain but only as a dream which crops up some nights.
