Could Iguin have lived in the time before the pact?
Spoiler!!!
Okay, that sounds dubious, but here's what I think:
First, their incredible mastery of magic—they definitely outshine their brethren in brimmed hats:
They fly without sylph slippers
Another brim's shoes/Iguin's shoes
2. They easily dispelled Euini's curse (note that Sasaran couldn't dispel it himself, so I assume he won't be able to dispel Euine's curse either)
3. They can teleport (Sasaran claims to have freed himself from the shackles of his physical body, but as we know, that's not true, and Iguin simply teleports)
4. They created a massive labyrinth-city (!!!)
5. Correct me if I'm wrong, but I think they wrote (drew?) an entire book (One of the characters said that the book Iguin gave Coco was homemade)
And secondly, don't you think it's odd that Iguin wears a brimless hat? He's the only one with a brimmed hat… maybe he was even one of those who made the pact, and then something went wrong? (Sounds doubtful, but it's possible!!) Judging by what we've seen, there's a certain element of madness in their character
And thirdly, I can't be sure, but I think in one chapter, Sasaran was clearly interested in Romonon's magic, while Iguin seemed completely uninterested. Moreover, the Inis scold Sasaran and tell them to leave. So it's either disinterest or mission priority
By the way, if what I wrote in the last post is true, they can't heal? Maybe Iguin wants healing magic to return?
And then there's this shot
Not a single familiar brimmed hat. Maybe these are hats from previous generations?
