Finn as a rarity among the elves in that the is hopelessly addicted to hard liquor. Driven from his home by his habit and the bad temper associated with it, he eventually found his way to Weepingbell. With little cash and plenty of time on his hands, he began venturing to the edges of the Desolation to gather up the stray horses of those lost to the Desolation’s hazards. This new trade brought him income and the ability to buy drink once again. Prosperity leaves him enough cash to get drunk, which is the condition he usually stays in until he has lost his shirt.
Unfortunately, his animals tend to suffer while he is in this condition due to neglect and the laziness of his hired hands who only do the minimum labor needed to keep the animals alive before heading home to avoid his drunken rages.
