Sammy has been at Camp Half-Blood on and off since his creation back in 2012, the duties of being a cat guardian constantly beckoning him to stray away from camp. However since he and his boyfriend rooted themselves at camp, he always comes back as soon as he possibly can, not wanting to be far from Elliott for long.
Often described as being the human embodiment of the term known as 'Cinnamon Bun', Sammy is always the nicest person in the entire world. It almost seems as though he doesn't have a single mean bone in his body. Always a bundle of joy with a smile that could light up any room. Sammy is also extremely talkative, with people he feels comfortable with of course. If he's comfortable around you then it's hard to actually get him to shut up for more than five minutes, but if he's uncomfortable than he'd more or less end up hiding behind Elliott.
Some could argue that Sammy is incredibly childish, and they are 100% correct. A cute and hyper goofball who would prefer to be in Elliott's arms over doing most things in the world is also a very accurate description of him.
For years, the gods and goddesses have watched on while the humans developed through the years, as they advanced both personally and technologically. Lately one thing has become quite clear to them; humans have a habit of being very irresponsible when it comes to their environment and the animals that reside within that environment. They came to a decision, fearing for the safety and longevity of their sacred animals, they have decided to create a special group of nymphs to help protect their sacred animals.
These nymphs’ life forces are each attached to the animal they are a nymph of; if that animal becomes extinct, the nymph will die. The gods considered the fact that here are thousands of animals and creatures that roam the earth, but not wanting to over extend their powers, they have decided to only concern themselves with the animals that are sacred to them.
When they aren’t out in the world helping other nymphs and helping to protect their animals, they spend their time at camp.
December was the month of Sammy's creation, Christmas day to be more specific. Upon creation, his first task was to help cats in shelters and give them to kids for Christmas. He'd leave them in a basket and a blanket on family door steps. The task didn't last all that long, considering it was just for the one day. So after that he just continued to rescue strays. Sammy continued to do this as well as overall protecting as many cats as he could up until December 2016. At this time, he came to camp.
Prior to Sammy coming to camp however, he met someone who would later become the most important person in the entire world to him. It was December 21st to be specific and Sammy was in New York at the time. It was there that he met his soon to be boyfriend Elliott. The couple fell for each other almost instantly, and eventually (as stated above) they would go to camp together.
