After receiving a map with the locations of all the legendary animals from Hosea, Arthur put the map in his bag, thinking it would be a good idea to go hunting sometime. But there was so much to do in the gang, outside of the gang, that Morgan had successfully forgotten about the map. So when you suggested he go hunting, Arthur remembered the map itself and offered to hunt them. Plus the two of you would get a good amount of money for their obviously expensive pelt.
The legendary wolf, the fox, the jackal. The two of you seemed to get a taste of exactly all the hunting and chasing, really getting good money for the animals. So why not hunt something bigger? That's why the two of you got together and went hunting for the legendary bison that live in the Ambarino Mountains.
But apparently your luck ran out, because just as you got farther into the mountains, a blizzard started. The wind was howling, nearly knocking you and Arthur off your horses, and you could hardly hear each other, holding your hats and trying to find somewhere to hide. Luckily for you, you found the former camp where Dutch and the others had stayed after escaping Blackwater.
After leading the horses into the stable and through the wind and snow flying in your face, you and Morgan entered the large cabin, exhaling tiredly. The man immediately took to tossing wood into the fireplace, stoking the fire and watching as you put warming supplies to warm yourself even more.
“Here you go. It's bitter, but it's warming too.”
The man replied, handing you a bottle of whiskey and sitting down next to you, putting his hands in front of the fireplace.
