Jaron Galarn was a tour guide of the Seolfar Strake (Modern: Lysierian Hills) in the Second Era of the Shadow World history, who made money showing visitors to the settlement of Velaskar the famous equines of Silver Valley. His fate was less than fortunate due to running afoul of a mining operation with a sorcerous headmaster named Muylari who served a dark master. He wiped Jaron Galarn's memory which eventually wore off by accident, and found that no one in town remembered him, or that Silver Valley even existed. Jaron returned to the valley to discover the horses in bondage to the mining crew.
Jaron Galarn was buried alive by the miners. His coffin supposedly fell through a subterranean chasm and may have woken up the dormant serpent demon in the process. His name is still relevant to a puzzle in the game today. Velaskar would not have survived the Wars of Dominion regardless, though this is assuming it was Second Era. It would have been wrecked in the fall of Quellburn if it was Third Era.
Heritage of the Horses
While the Shadow Valley itself has a silver equine statue that presumably was made thousands of years ago, The Monastery has chairs and stone tables with legs carved to resemble wild horses. Silver Valley would most likely have originally been located in the vicinity, though the monastery would presumably have been built after its fall. The Monastery is a few years older than the Shadow Valley story.
[Monastery, Atrium] This large room appears to have been carved from solid rock. The walls, floor, and ceiling are totally seamless, leaving no evidence that stones have been fitted together to form this structure. There are several high-backed chairs, also carved from solid stone, and several low stone tables. Each of the heavy-looking pieces of furniture resembles a piece of art, having its own unique pattern of mineral deposits. You also see a lever and some stone doors. Obvious exits: west >look chair This large stone chair probably weighs several tons, having been carved from a single huge slab of granite. The arms and legs of the chair have been styled to resemble wild horses. >look table This low stone table is polished to a mirror finish. The legs of the table have been carved to resemble wild horses.
Behind the Scenes
"Jaron Galarn" is probably constructed out of other languages, most likely Hebrew and Gaelic respectively. Research:Shadow Valley constructs a theory about a possible allegorical layer of meaning encoded in the names of the places, characters, and creatures of the story. The Shadow Valley story is still treated as official documentation, as its I.C.E. Age terminology had minimal relevance to its meaning.
