I wouldn't say it's doomed just yet. I don't recall how things ended, entirely, but I do know that the man responsible for the creation and attempted spread of Uroboros was found before he could act. I also believe he was killed, but I don't know what the end result of the attempt was, or its overall effect on my world.

[And that's likewise cold, but it is entirely honest.]

The other virus can be countered. Hopefully nothing came of the one that can't be.
