So I was looking at a list of the Red Mage Weapons and noticed a weapon called Belah'Dian Degen which is found in the Gubal Library. I noticed a lot of the Gubal Library weapons seem to be old historical weapons, for example the Pre-imperial Garlean Revolver or the Royal Nymian Marine Codex, and Royal Nymian Marine Battleaxe.

1. Was Belah'Dia founded shortly after the flood?
2. Was it around the same time as Ala Mhigo was founded?
3. If so Was Belah'Dia made up of Amdapori and Mhachi as well which could have founded a second Group of Red Mages?
