Scholars Guild

After the Cataclysm that destroyed Equestria, the Grifix realized there wasn’t anybody left to record the events of the world. They started paying a lot of attention to writing books, recording history, studying magic etc. A big part of the City consists of libraries. They gathered books and scrolls from all around the world, even sending grifix out to gather them. 

Now the Frozen Empire is the place with the most written knowledge in Equestria.

It is the guild with the most influence and underguilds. Amongst those there counts the Herbalists Guild, which had a big raise in influence lately. Following the study of plants and sunlight they found ways to raise plants in special glasshouses, which allowed them to create new food sortiments for the grifix that fed on meat alone for hundreds of years.
