It was hinted at quite often in the last 10 Chapters. HE is the Brother, summoned from another World... or at least his Full assist.
I must be dense. Even after reading this chapters last page I didn't understand she was referring to him as her brother, the greedy dragon, though he is quite greedy when you think about it.
I mean, the dude is already a hero, a demon lord and a sage with creation power, a transmigrator and apparently now he's also a dragon? My brain turned off at some point.
There is no way polities and organizations will not want that island and let the adventure guild manage it. They go for war with less.
To be honest, I'm confused anyone owned the territory in the first place considering that it was supposed to be hidden before the sloth dragon ran out of power and pirates found it. So the place was basically some sort of myth. I guess it was nominally part of the territory.
I'm also surprised everyone is totally chill with unleashing infinite ores onto the world. The value of all those ores is basically going to either crash to basically nothing (bar the cost of mining, transporting and generally crafting with it) or if they artificially limit supply and keep prices high some people will be trying to smuggle ores out (which should be difficult considering it's an island which is difficult to access).
Well whatever, they just prevented a volcano eruption with the power of friendship and a bunch of other stuff.
