The Faedin religion is one of the official religions within Elyria. For that info, I'd recommend this site: https://chroniclesofelyria.gamepedia.com/Faedin
Faefoth is named after the Faedin religion. I just made up 'foth'.
Faefoth, my capital, will contain the Ameno (healing school).
Glassblowing is considered to be a peripheral to the other specialties. I will be prioritizing the core (Alchemy, Breeding, Health/Poison, Herbalism and Spiritual applications). As we attain enough interest, we will look into things like Glassblowing, since we will likely be a large consumer of it.
Vita Vinum is ran by Triabane Aegir, one of Faefoth's Mayors. If he chooses to make a separate guild for brewing, he can. Brewing is currently not affiliated with the Progenium. It should also be noted that the Progenium and the Talqamar (another large university in the Duchy) is merging.
As of now, I believe Baron Shield is planning to take an internal peace-keeping approach. However, he has my full support however he decides to provide Faefoth sufficient defense.
Regarding your baron question: Officially, yes. That is correct. However, I will still be providing significant support to all of Faefoth's settlements, including the Baronies. The Duke and I are aligned on this topic. Faefoth is a Grand Suntree (2x). I would have to wait until D&SS for an exact number, but, due to the expected population, resources, and size of Faefoth, I am expecting at least 2, perhaps 3. I think it would be fair to have one Baron for every 4 Settlements.
I plan to fill the default settlements that D&SS provides and nothing more. I would like Faefoth to remain wild, relatively hidden from the rest of the world. I believe Faefoth currently has a total of 6 mayor/baron titles (counting my own). About half of these have defined Settlements.
I will provide a detailed posting of the Settlement info.
