Hobbits originated in the northern section of the Vales of the Anduin, before splitting into three different types, Fallohides, Harfoots & Stoors. If they once dwelled near the Anduin, how come their presence is not portrayed within the mod?
Harfoots
History: Harfoots were the most common type of Hobbit, with and lived in the Vales of the Anduin and the Misty Mountain Foothills. They dwelt in holes called Smails, and liked highland and hillside terrain. They were on good terms with Durin’s Folk. The Harfoots were the first race of Hobbits to leave the Anduin in search of less hostile lands after the darkness started to spread within the Greenwood.
Harfoot Structures
Ruined Smail: Ruined Smails would be rare buildings that spawn the Vales of Anduin, Anduin Hills and the Eastern Misty Mountains Foothills. They would be slightly more common than Ruined Fallohide Houses. They would be very similar to the current Smails that spawn in the Shire, but without light sources, glass and rotten wood. They would be slightly smaller than the Shire Smails. Parts of the building could be caved in. Very rarely, Dwarven bricks would be used instead of cobblestone/stone bricks/bricks. If you are lucky enough to stumble upon a Smail with a chest inside, it would contain general loot like string or a pouch, maybe a few coins and plates, and if you’re very lucky, a Dwarven goodie or two. A few Ruined/Collapsed Smails could spawn very near each other, creating a Ruined Smail Village. Aside from wild animals and Orcs, no other mobs would spawn.
Collapsed Smail: Collapsed Smails are exactly as they sound. They are the aforementioned Ruined Smail, but with 100% of the roof having caved in. Being shaped like an odd hill, they are easily overlooked, and are far more common than a Ruined Smail. But do not dismiss them quickly, loot may linger beneath the fallen dirt. A few Ruined/Collapsed Smails could spawn very near each other, creating a Ruined Smail Village.
Fallohides
History: The Fallohides dwelt in houses in forests near the upper reaches of the Anduin River, Eagles Eyrie and The High Pass. Living also in this area was the ancestors of the Rohirrim, and the Northmen, it is likely that they also mixed. Fallohides were great lovers of trees and nature and friends of the Elves. They were skilled hunters, but lacked in the art of farming and agriculture. Like the Harfoots, the eventually left the Anduin in search of less hostile lands after the darkness started to spread within the Greenwood. They are the least common of Hobbit types.
Fallohide Structures
Ruined Fallohide House: Rotten Fallohide houses would be rare buildings that spawn in Forests within the Vales of Anduin and the Anduin Hills. They are made out of rotten wood or rotten wattle and daub and cobblestone/stone bricks/ bricks, and half-collapsed in areas. Some would have a slight Rohirric feel to them, architecture wise. Very rarely, a house could spawn with Wood-Elven Bricks instead of cobblestone/stone bricks/bricks. The houses seem to be a cross between a long cabin and the current Hobbit homes that spawn in the Shire. Some homes would appear to be nothing more than the foundations. If you are lucky enough to stumble upon a house with a chest inside, it would contain general loot like string or a pouch, maybe a few coins and plates, and if you’re very lucky, an Elven goodie or two. Some houses could spawn with an abandoned animal pen beside it. A few Ruined/Collapsed Fallohide homes could spawn very near each other, creating a Ruined Fallohide Village. Aside from wild animals and Orcs, no other mobs would spawn.
Collapsed Fallohide House: The same as a Ruined Fallohide House, expect that all of the building is collapsed. A few Ruined/Collapsed Fallohide homes could spawn very near each other, creating a Ruined Fallohide Village.
Stoors
History: The Stoors lived in the Gladden fields and the Vales of the Anduin, and mainly consisted of fishermen. They prefer to be near water, and are the only Hobbit type known to use boats, swim and use shoes (only when muddy, though). The Stoors remained near the Anduin long after the other two Hobbit types had departed the lands, but did eventually leave. Unlike their kin, they went West under the Misty Mountains and settled in many different lands such as The Angle, Swanfleet and Dunland. When the strength of Angmar grew, The Stoors of The Angle and Swanfleet fled south to Dunland or to their kin in the west.. Some returned to the Gladden fields (to which Sméagol and Déagol belonged to). Eventually, the Stoors of Dunland departed north for the Shire. Some Stoor villages in the Gladden Fields may have survived past the War of the Ring, even after RingWraiths sought out the Hobbits in search for Bilbo.
Stoor Structures
Stoor House: Stoor Houses are very rare. They are very similar to that of the current Hobbit homes that spawn in the Shire, except that they have a dock out the front. These homes spawn in the Gladden Fields only. Next to the dock is a small Hobbit boat. They have normal Hobbit house loot, with fishing rods and, on occasion, a Dunlanding Trident. They are made of wood (of the closest type of wood to the structure), wattle and daub, glass and cobblestone/stone bricks/bricks. The houses have a certain Dunland flair to them. Inside the house, there is a chance that Stoor boots can spawn inside the chests. The Stoors are a part of the Dunland Faction, but Dunland crafting tables and banners do not spawn inside, though. Inside the houses, Stoors spawn. They are slightly taller than their kin, and have wider arms. They do all the things normal Hobbits do. When it rains, the put on a pair of Stoor boots.
Stoor Village: A Stoor Village can only spawn in the Gladden Fields, and are just a bunch of Stoor Houses rather close together. Stoor Villages are very rare.
Ruined Stoor House: Ruined Stoor Houses spawn in the Gladden Fields, Swanfleet, Dunland and the Vales of Anduin. They are derelict, rotten versions of the inhabited Stoor House. They are 3x as common as an inhabited Stoor House. They are made of rotten wood, rotten wattle and daub and cobblestone/stone bricks/bricks. Some buildings appear to be no more than the foundations. Aside from wild animals and Orcs, no other mobs would spawn.
Ruined Stoor Village: Ruined Stoor Villages spawn in the Gladden Fields, Swanfleet, Dunland and the Vales of Anduin. They are derelict, rotten versions of the inhabited Stoor Village. They are 3x as common as an inhabited Stoor Village. Some buildings appear to be no more than the foundations. Aside from wild animals and Orcs, no other mobs would spawn.
Charred Stoor House: A version of the Ruined Stoor House, except it’s made out of charred materials and only spawns in the Gladden Fields. Twice as common as an inhabited Stoor House. Some buildings appear to be no more than the foundations. Aside from wild animals and Orcs, no other mobs would spawn.
Charred Stoor Village: A version of the Ruined Stoor Village, except it’s made out of charred materials and only spawns in the Gladden Fields. Twice as common as an inhabited Stoor Village. Some buildings appear to be no more than the foundations. Aside from wild animals and Orcs, no other mobs would spawn.
In All Villages: In each Hobbit Village, one Windmill, one Barn/farm and one Tavern (Similar to that of the original Hobbit Taverns, but with a hay roof). Windmills and farms will be much less common in Ruined Fallohide Villages, and Barns twice as common. If these spawn in a Ruined Village, they will spawn with the respective rotten or charred materials. If the structures do not spawn in a Ruined Village, they will spawn with the correct materials. They are very similar to their Shire variants.
