If not for the Pope's glorious martrydom, the fate of the civilisations in Holletta would have been very different.
Even though the giant that Hao Ren captured was still of sound mind, he still bore thoughts of annihilating Hollettan Civilisation. And at that point of time, the guardian was threading on a very fine line between mercy or destruction for the planet. The Pope's sacrifice pushed the giant away from the brink, and allowed him to let go of the futile need for vengeance as well as retribution. The mention of such a great elder only evoked respect from Hao Ren.
