The clerics wished to give the impression it was the real Kahless who had returned from Sto-vo-kor to once again lead his people. When Worf visited the planet Boreth, the clone of Kahless appeared to him. With the USS Enterprise-D having been sent to bring Kahless back to the homeworld, Kahless accompanied Worf back to the ship, confident from Worf's tales of his comrades that they were honorable companions, approving of Worf's recognition of his Klingon heritage. Gowron attempted to test Kahless with the Knife of Kirom, but Doctor Crusher's subsequent analysis of the DNA confirmed that the blood on the blade and the blood of Kahless were identical.
