1- SCH tomes don't have the same geometries or rituals that ACN/SMN tomes do, they're instead texts on strategies. The in-game models for SCH weapons have text instead if a circle with angles to show the difference in who can equip it.
2- Fairies are a kind of construct in the same family as elementals, but not as powerful, according to some old lore. I've taken it to mean they're like a minor nature spirit but my interpretation may not be everyone else's.
3- Nym was an old empire during the same era as Amdapor and Mhachi (I wanna say 5th but I'm at work and can't check for sure). The other two were famous for fielding WHM and BLM but Nym used squads of 3 MRD led by 1 SCH in battles. Nym died out due to a plague that turned its people into the Tonberries we see in WP and the SCH quests (which some speculate was caused by the war between the three magical empires).
