Darth Momin's destruction of a city

Between c. 1100 BBY and c. 1000 BBY, the Sith Lord Darth Momin was guided by the dark side of the Force to select and destroy a city. Momin created a superweapon, with the help of his acolytes that possessed the power to destroy the city. The superweapon began to slowly destroy the city as the inhabitants realized their fates. But then several combat hardened Jedi infiltrated the superweapon, and even though his acolytes put up a formidable defense it was not enough. The presence of the Jedi interfered with Momin's concentration with the weapon, causing him to lose control of the engines. The superweapon fired and obliterated the city in an instant. The weapon blew up, killing Momin but his consciousness survived in his mask. Thousands of years later, Momin told his story to Dark Lord of the Sith Darth Vader on the planet Mustafar.
