The Great Transformation

In the year of 2799, when the sorcerer Bolsh Thornson was 17 years old, a Human adventurer named Blep Sakrun stopped in Lyllon on his travels searching for adventuring work. Blep antagonised the small town's populace, attempting to order them around and threatening to fight back when his demands were ignored. Although no one in Lyllon liked the adventurer, few actually stood up to him, many believing he would be on his way out of town soon. However, Blep stayed for at least three weeks, and during that time the people refused his orders.

Bolsh was among the few who stood up against Blep, although he tried to stay out of taking too direct of opposition. Blep's anger at the people for not listening to him grew to the point where he got physically violent. After being refused when demanding a bystander buy a drink for him at the tavern The Ancient Fire, Blep ran the man through with his longsword, leaving him to bleed out and die. Bolsh called out Blep, who challenged the young Dragonborn to a duel. Bolsh's anger grew until he snapped, and his dormant magic flooded out in an enormous burst of power. The wild magic let loose the spell polymorph in a ripple effect, hitting the entire population of Lyllon and magically transforming them into sheep. Now afraid, Blep fled for his life.

Supposedly, Bolsh apprehended the fleeing adventurer by throwing a transformed rival of his at the man, killing Blep. He then apparently kicked the rival into a brick wall, killing him as well. Bolsh's story may not be entirely accurate, as he was prone to exaggerating retellings of his past. Either way, Blep Sakrun somehow vanished, and Bolsh left Lyllon soon after. Bolsh claims that the inhabitants of Lyllon were not turned into ordinary sheep, but "sheeple", who could talk and think for themselves. Whether or not this is true is not clear.

Soon after the Great Transformation, Lyllon began to fall into ruin.
