1010 A.D.

Keystone T-2

-Wazuki attempts to kill Serge, thus totally losing it in the process and
becoming Lynx.
-The dimensions split depending on the outcome (see Home, Another timelines).
-Home/Another splitting is possibly caused by Kid's time traveling and the
gravity of Serge's life/death on the continued existence of reality, which is
threatened by the Time Devourer.

Home Timeline

allowed to live.

-Without FATE to instruct him, Kiki's father becomes a fisherman.
*Mel is born.
