For years the swordsman Kenshi traveled the world in search of worthy opponents. When a mysterious elderly man named Song offered to show him the location of Sento, an ancient sword worthy of his abilities, Kenshi succumbed to pride. He followed Song to a tomb wherein lay the Well of Souls. When Kenshi retrieved the sword, spirits of ancient warriors spewed forth, blinding him. Song then revealed himself to be Shang Tsung. He consumed the souls, leaving Kenshi in the dark labyrinth to die. But Sento called to Kenshi. It led him out of the tomb and revealed his lost heritage as a descendant of the warriors who had been buried there. Kenshi vowed to slay Shang Tsung and free the souls of his ancestors.
Guided by Sento, his ancestral sword, Kenshi destroyed Shao Kahn and saved Earthrealm from Armageddon. But he had not yet exacted revenge on Shang Tsung.
The elusive sorcerer had hidden himself somewhere in Outworld. Jax allowed Kenshi access to a newly developed portal that permitted travel among realms. In return, Kenshi agreed to serve the fledgling Outerworld Investigation Agency. After countless missions he finally located Shang Tsung. With a roar, Kenshi plunged Sento through Shang Tsung's chest. The magical sword drew the souls of Kenshi's ancestors into itself, leaving Shang Tsung a withered husk. His vendetta fulfilled, Kenshi left Shang Tsung to die alone and powerless.
