It's always a pleasant surprise when your job is done for you. The Jedi, while quick to make himself a nuisance, had fled when he was so clearly outmatched by [member="Darth Ferus"] . During his escape attempt, he quickly attempted to signal for backup, but there was no comm signal down here, so that wouldn't be an issue. He then proceeded to rip into the ceiling, cutting it with his saber, before ripping it down with the force. The Jedi made his getaway, safe as he was behind to falling rubble and metal. While he managed to escape with his life, the fool didn't realize that he had completed a portion of a terrorist operation, Korin was going to have to set some charges to permanently close the tunnel, anyway.
Turning from Alderaan's newest wall, Korin jogged the rest of the way to his target, it wasn't far, he was sure [member="Doctor Agnusdei"] and the Darth could keep up easily enough. Holstering his pistols, he slung the bag full of explosives off his shoulder, setting them down on the floor. Sitting down in front of the bag, he opened it up, viewing its contents.
There was the big bomb, which had to be set about two feet from where he was sitting, as well as twelve thermite charges, for demolishing the hallways surrounding them. Well... only need nine now, thanks Jedi. He made quick work setting the charges, one on each hallway ceiling, as well as two on the walls. After verifying that all of the charges were set to the same frequency, Korin jogged back to the bomb, carefully removing it from the bag.
Setting the bag, along with the three remaining thermite charges to the side, he sat down cross-legged before the modified explosive. Interlocking his fingers, he produced a resounding crack, loosening up his hands for the delicate work of arming this beast. It wasn't as simple as just slapping it on the wall, like the others.
