'A Fifth Dimensional expert who can strike to kill the likes of Xagu.'
The thoughts of Urlgan were much different than what his actions dictated. He was calm and calculating. As for why he had sacrificed Xagu, it was because he didn't have the patience to deal with the matter.
If he gave up a substantial amount of resources, he might be able to shorten the time to just 10 years, but what good was that?
The amount would be substantial and would put a dent in the coffers of the Empire. The more powerful the Ninth Dimensional expert was, the more expensive it would be.
He was unwilling to pay that price just for the sake of one Xagu. But if he let Xagu resurrect the slow and normal way, a few things would happen.
