all genetic engineering experiments done by the doctors, that's where the budget of the council was going, to the doctors job. The world is an post-apocalyptic future, 70% of the world is desert, most humankind died, so they are working in doing an "improved" version of humans, more empathic and therefore less prone to wars. That's why they have the strange empathy-telepathy in between them. No. 1, which is one of the latest work of the doctors, it's an even better version and his empathy and feelings can be overwhelming to the rest of the council and it even reaches normal humans. But... he isn't really the latest version, I think, but Mathroska. Her type of empathy is much more subtle, but powerful, She makes people around her strangely happy, both no. 5 and Viktor said it, and she feels all around her, from all lifeforms. Not only humans. It seems she is eating all the time because the plants and animal impulses that are around her.
