Morgan had an uneventful childhood, aside from being a reckless teenager and getting into minor trouble for the fun of it. Because of this desire to seek adventures, they ran away as a teenager and caught a ride to the wastelands, eventually making their way to Recom and befriending a group of pirates. They liked this new life, so they were committed to it and actually become good at scavenging. They and whatever team they were hanging with would take advantage of decaying towns, looking for things to loot. 

When they and one of her closest partners were injured in a collapse, it was between them and the other girl on who was going to take the others organs to survive. Morgan ended up being favorited in the moment. Morgan doesn't like to think about it, as if they should "feel bad." It sucks their friend died, but what's wrong with wanting to be the survivor ?? 

They ended up developing a mutation from one of her colleague's toxic plants. The plant bit them, causing an overabundance of blood as a reaction. Morgan constantly develops bruises and the bleeding has spread to their eyes and mouth, giving them a pink tint.

After many years, they grew actually tired, physically, from the workload and knew that they couldn't start fresh without stealing a bunch of cash and going back to Evelow. They also took a supply of fresh blood, as theirs was causing them to bruise and over saturate her skin and thought they'd find someone to make them well again. They started their return to Evelow to visit the only bridge they hadn't burned, an old friend named Cora who changed a lot more for the better since Morgan left her and wasn't as patient with Morgan's outlook on life. Nonetheless, Morgan found new friendships with Cora's roommates and their friends, and realized that they genuinely felt comfortable in this new home, and to keep it they might actually have to change herself. 

Although their relationship with Cora diminishes (it's what cora wanted), Morgan ends up with a new group of friends, one of them being her eventual girlfriend, who is willing to travel to Recom behind Morgan's back to find a cure for Morgan's mutation. 

The mutation does end up taking a toll on their health, but what better place than Evelow, the shining example of innovated genetics, is there to be ? Well, when Morgan tries to find a cure on their own terms, it ends up costing a little more than what they bargained for.
