So here are some of the things that made me think of this theory:
I think it said somewhere Smedry siblings have similar talents.
In the case of Attica and Kazan, one talent teleports things, the other talent teleports you.
Firebringer's lenses shoot out fire, while the glass they use for torches sets itself on fire.
Then there's Shatterer's lenses that break glass, and Restoring glass which breaks and restores itself, perhaps 'forgetting' it was broken.
So, I think that the Breaking talent and forgetting talent are related, and that someone with the forgetting talent can forget things like injuries and maybe aging.
