The Night Sky Marveler is a mole-like creature found across the wider Reach. They are nocturnal, and despawn during the daytime (except when underground). Their claws and meat are valuable, but their fur is an exotic and prized item held in high esteem by Reachmen.
"Porcelain armor has exactly the exoticness that seems appropriate to the stone-worshipping people of the Hammerfell. Like glass armor, its name confounds expectations, which inherently pushes it into the fantastic (and look how glass armor is accepted nowadays). Of course raga porcelain is enchanted and blessed by the Gods through the hands of its craftsman, and thus a viable (and beneficial because of its lightness) form of protection.
Giant snails found in the Bjoulsae regions of High Rock and Hammerfell. (Bjoulsae Basin and Dragonfields)
Basically the margin art of medieval manuscripts writ large and lifelike. These beasts are often farmed or used as pack animals by merchants on the roads. Dangerous "dragon snails" are larger and can be found as hostiles in the wilderness.
Architecture for the tribes of the Bjoulsae River basin. These semi-nomadic peoples live in encampments much like orcs, ashlanders or Reachfolk, though the riverfolk often live in closer proximity to their settled Breton and Redguard counterparts. Most riverfolk settlements are on or near the floodlands of the Basin, and are built up on wooden platforms on stilts. Brightly-colored tents made of thick canvas can be easily packed and relocated on boats in the event of relocation.
