As i recall, most organized Otaku met their demise at the hands of Pax and Winternight agents....
Very, very, very wrong. The post-Arcology otaku clash was between Overwatch (the bloated monstrosity it had become, some 150+ otaku), Deus's Network members (whom they were trying to hinder), Ex Pacis (led by Pax who wanted Deus back together so she could destroy him), and Winternight (who was working with Pax, but who wanted to destroy the Matrix and usher in the end of the world). Otaku outside of that fight may have died in the crossfire or for other reasons, but there were plenty of tribes that got along just fine outside of that little clash.
Hmmm, I remember that differently, Guess I got some re-reading to do.
Thanks!
Both are equally plausible. It depends on how much you read into System Failure about the battles that broke out between each AI faction and to what extent it drew unaligned Otaku, which was the vast majority of them, to be honest, into their war. System Failure wants to suggest that it was basically WW2 in the streets between tribes, even or especially tribes that didn't start out having anything to do with the three AI. At the same time, Wyrm is generally right that most Otaku had nothing to do with Deus or the others, so the conflict was generally contained to a minority of Otaku. I'm inclined to agree with Wyrm, but I can't say for sure.
ANYWAY, I'm pretty sure the Mosaic doesn't exist. It was always being threatened, and neither it nor Tenchi, the sysop, have been mentioned since Shadows of Asia.
