The education thing is close enough. I think you underestimate how harsh it would be to grow up with nomads who have absolutely no trust in you and only tolerate your existence based on whatever utility you provide to them, but it's come so far from where it started that I am just going to call close enough.
I am still lost on the Epilepsy weakness, though. How many times if your life have you had Deja Vu? I may be odd, but I can probably count on one hand how many times I've had Deja Vu. Not sure how that will come up in RP. What even is indeterminate memory? Are you saying if he doesn't remember something completely, he has a seizure? Can you give an example so I can understand this better?
