Back when Izroth defeated Falcinean, and even after eliminating 2,000 Pzenium warriors, he did not gain any fame for the Pzenium kingdom. Yet, after dealing with Gakhan, his fame immediately shot up by 1,000 points, which was by no means a small amount.
This could only mean that Gakhan's existence in the Pzenium kingdom was of significant enough importance to affect things on a sizable scale. However, the reason could not be due to his individual combat prowess.
It was true that the Pzenium kingdom respected strength above all else, but, in terms of raw combat power, in Izroth's eyes, Gakhan was not that far off from someone like Falcinean. Rather, if not for the Scarlet Sand Spiders and Gakhan's unique physique capable of housing the creatures, it was likely that he would outright lose to a warrior of Falcinean's caliber.
If that was the case, why did his fame in the Pzenium kingdom not increase by even one point after defeating Falcinean?
