[AU Basics]
Devit and Jasdero Walker take Allen's place in canon.
They were raised by Mana, and before Mana died, he implanted his memories into Jasdero, the same way the 14th had implanted his memories into Devit. They trained with Cross and canonstuff happened. etc. The two have matching opposite Crowned Clown Innocence now.
In their world Mana and the 14th were the Bonds, and they turned traitor. The Musician is a separate Noah, who awakened within Allen. This makes Allen a Noah with the powers of the Musician, not a traitorous Walker.
Point in canon: After Cross tells them about 14th and Mana, but before Kanda's Wisely-induced flashbacks.
