My Queen have you meet any other kuros after you was awaken by Kaos? And If you have have they come back to Kurosia or live in new Kurosian villages?

Lost Queen : I was the sole survivor of The Fall, at least that I know of. I was attempting to lead my people out of the city via our castle’s Catacombs, but somehow, the caves collapsed with me being the only one to make it out. If someone escaped before me, I did not see them. I don’t remember much after that, but I know Eon and I faced each other in battle and he froze me in emeralds. 

It’s been almost 30 years since Kaos woke me from my stone slumber. I haven’t heard or seen another Kuros other than Cynder. Either they’re hiding very well, or they truly are all dead.
