"Is this... a God?"
When Revin and Nipede arrived at the temple with their Knight troops and saw the divine object that the Maya were praying to, both of them let out somewhat uncertain voices.
Especially Revin, who very directly said,
"Is this what a God looks like?"
No wonder he said that.
In the modern continent of Akasha, it's not that there are no religious beliefs, but the gods of those religions mostly have either majestic or sacred images—typically humanoid in form, or at worst dragons, snakes, beasts, and other such vivid biological images.
Yet the God worshipped in this temple was merely a square block, which to Revin and the others indeed seemed quite strange.
Let alone them, even Reiger hadn't imagined before that the God the Maya kept mentioning would be such an entity.
