Hercules laughed despite himself. The entire thing was funny to the Demi-God because he had just blurted out something that he had kept inside his heart for nearly his entire life, yet he was surprised just how much better he felt now that it was off his chest.
Darius' eyes gleamed as he heard Hercules murmur. He was naturally surprised that the Greatest Hero himself would make a similar reaction to Theseus, but then again, it made sense.
Achilles was a bad example of a Demi-God - or rather, a good one - because as a mortal, he had been born to a human king and a non-human mother. That same mother had broken many rules to bathe him in Styx water, which forever barred anyone else from doing so later.
She had been captured and penalized heavily, but young Achilles was unaware of all of that. He had grown up with his king father, groomed to become the warrior he was today, using his invincibility to win battle after battle.
