My grimoire floated in front of me. Giving it a slight caress, I explained, "my grimoire is essentially the tool of my awakening. To an Archfey, awakening means the merge of old and new memories. It allows us to make the choice to remember our past lives." Seeing their confused looks, simplifying it would be best. "The easiest way to explain is with the memory charm.  Obliviate . If you were to cast the charm on someone and do an extensive job of making them an entirely new persona, they will still retain their personality. The only thing that is different are the memories of the person. Now, that would cause serious trauma once the charm was lifted, but we Archfey are different since our memories are all part of our soul."
