The soft, bluish fur of the Alolan Persian is the most comfortable substance found in all of Alola, and was used to line the beds and carpet the floors of the island's royal palaces. This comfort was equaled only by the discomfort associated with receiving Persian fur blankets as gifts of the crown, for many who slept under them would never awaken, their throats slashed in the middle of the night by a Persian claw.
Although the odd Meowth granted by the crown would evolve over the course of its natural lifespan, Persian were so closely associated with royalty that the act of owning a breeding pair of these pokemon was considered treason per se; it is notable that the blue jewel on their foreheads is identical to those in the royal crown. Only a king or queen could gather enough Persian to gather blankets out of their shed fur, and remaining on the throne was if anything more difficult than ascending it; Persian are remembered as the trained assassins of tyrants, but many monarchs undoubtedly removed real threats to their power as well.
Accounts vary as to the method of assassination, for while Persian are elite hunters, it is unclear whether they could've used the scent of their own fur to stalk their prey, or to slay their victims (typically powerful nobles with many bodyguards) in the middle of the night. But it is hard to accept the legend that the claw itself, shed from its owner and hidden in the blanket, was the weapon of choice. Yet invariably, those awarded a Persian blanket went into hiding or fled the domain of the king in question, even in those rare occasions when a young and naive monarch only wished to share the comfort of their favorite pet's fur.
