Grogar

King Grogar is an evil demonic ram necromancer and the emperor of Tambelon, a 3000-year-old land that existed long before Equestria. before he was defeated when the ancient bell was ranged, vanishing him and the city into thin air. He was a king that sought power, specifically through creating darker versions of pony magic, including Somnambula's Tempus Objectus after he killed her, and used it to bring back Darkspawn superweapons lost and forgotten to time, ignoring his uncle Baphomet's prophecies that he would be defeated out of denial, and losing it as a result, and ensuring it didn't come true by corrupting the parents of Gusty the Great when she was young, until his henchmen were unable to reveal their failure to obtain Gusty before they were lost, along with his power. Downright angered, and still not listening to his uncle, he sought a powerful artifact called the Map of Infinity, which was so powerful it could dispel prophecies and change fate, all by acting as a fifth-dimensional relic that can predict several possibilities to avoid prophecies, and despite being split into four pieces for safety, he found the first piece that already predicted locations of which he can go to grow in his power. When he found the map pieces that were scattered despite interference from Gusty the Great, he found enough power to dispel many forms of power, eliminating virtually any chance of defeat. However, when he sought to first control everything in the world starting with the weather through Cloudsdale, Gusty defeated him despite being scared into submission by his cockiness and underestimation after years of denial of prophecies. Thus, after his defeat, he was robbed of the Map of Infinity, and locked up in Tartarus. Baphomet, angry that he didn't listen, forbidden anyone from retrieving, saying 'He wasn't going to learn anything if he didn't see the consequences of his actions. If he has to be in Tartarus for an eternity to teach him a lesson, then that's his fault!". Thus, Baphomet named himself the new leader of Tambelon while Grogar would spend the rest of his days abandoned and staying in Tartarus. He has a voice on par with Earl Boen (Dr. Silberman in Terminator franchise.)
