Scale Sourcerer

The being controlling Klavier Gavin, SCP-048, a doll known as Red, and a few other key players in the wider Lucas' Diary canon. Though he's one of the newer members to the server, he's managed to cement himself as the 3rd most talkative member of the server, and leaves a hefty impact on most worlds of the server. Among the "people upstairs," he's the most likely to interact with the tuppers (aside from Sadie, who is a character in and of herself), the least likely to get into nsfw situations, and the least artistically talented.

Background
Scale was a simple kid from the same place a lot of the other people upstairs came from, going through school a couple years faster than the others due to being a strange senior. He entered the server on January 11th, 2021, though he had known about the server for a year beforehand, in order to defend his boyfriend's honor during a Homestuck-related meme war. He's integrated himself into the server ever since, through little more than sheer force of will and enough likability to not get on the other members' nerves too much.

Canon Interference
Though Scale has largely remained outside of canon like the other "4th-wall gremlins" (people behind the tuppers), until the completion of a game known as Everhood, and the introduction of Otami as a canon presence. Since then, Scale introduced Red, the game's main character, as a body for him to occupy, working out a deal with the previous owner of the body. Red has thus acted as a way to introduce other characters to the Diary (through the bots server) and a player in stories related to the Friday Night Funkin' universe due to Red's rhythm game roots.
