When Sparkling Creek Valley was created, it was all about the wolves. For the first four years, wolves were almost exclusively the only animals joined, with a few hybrids and dogs thrown in here and there. Even today, the wolves easily outnumber the other species, though the pure blood of the wolves in the Valley is slowly being mixed with domestic breeds, to the point that very few Bloodlines exist that have 100% pure-wolf genes in their decendents.
To date, about 1540 pure wolf characters have entered the Valley, with around 400 of these being born here. The majority have been Gray Wolves, followed by Arctic Wolves, and a fraction of Mexican, Ethiopian, Red, Arabian, and European Wolves.
