Y’all think he’s Euden from another future?
Pretty sure he’s Aurelius.
For starters, his partner is Parallel Zodiark
Second, his bio says:
A mysterious man who stands in the prince’s way at every turn and claims to know a great truth. He seems to know the prince quite well, and his eyes glitter with a warm, intense light when he looks upon the boy.
Specifically the part where it says:
“He seems to know the prince quite well, and his eyes glitter with a warm, intense light when he looks upon the boy.”
One last thing, when he introduces Cassandra, she says “Well bless my stars, I never thought I’d see the day that Au-”
“Audric, my name is Audric”
"Heh Heh. Fair Enough, ‘Audric’ "
Euden’s doesn’t have a name starts with “Au”, his father, Aurelius, however, does.
Spoilers
Auric reveals who he is in the last part of his adventurer story. I won’t say who in case you want to keep theorizing ;D
