Darth Mauls mistake
This story takes place during obi wans visit to mandalore to speak to duchess satine and when maul takes over mandalore
Darth maul is talking to Obi wan while he is being held down by the mandalorianguards and he is ranting on about how he never planned to kill Obi wan but to make him suffer for what he did to him. But Obi wan's frustration grew at maul as he hints that he plans on killing satine and Obi wan couldn't do anything unless he used the Darkside to kill everyone but he knew that satine would never forgive him for killing especially because they were her men. And he also rembered about the council they would surely expel him. But as he conjures over his next move he hears mauls light saber ignite and a crimson red covers his face and in a flash satine has been impaled by the blade. The guards realease him only for him to hold her in her last breath and overtaken by his dark and deep emotions he reaches out into the force and draws on the darkside and all the guards are taken off their feet even savage oppress and choked all expect maul just standing their in satisfaction on how Obi wan failed to keep calm. Darth mauls satisfaction turns into fear as Obi wan takes the dark saber off his belt and draws the blade to maul and Obi wan screams as he lunges at maul.
(I know maul used the darksaber too kill satine but I wanted to use the word crimson so ️)
