El Pasto was born from the second litter of his parents, alongside fallen siblings. The pack was hardly stable during his birth, and he feels lucky to be alive. His keen nose made him adept at foraging for useful herbs, and the herbalist before him took notice of it. He wishes to become much greater at his job, and would hate seeing future puppies or adults die of treatable illnesses.
He became close with his older sister after the pack became less chaotic, with neither of them allowed to bear puppies of their own, they agreed to foster puppies whenever they were found.
