And at the end of Volume 20, Tiamat seems to have either found a lead, or actually found one of them. We don't know which one it is just yet though most think it might be the Telos Karma.

...Or was it actually mentioned that it's the Telos Karma? I remember someone saying it, but I didn't see it when I read the baka-tsuki translation, and the Vol 22 spoilers' poll only has "innovate clear" possessor as an option instead of it and the telos karma wielder.
