The High Mage returned Tarna's grin.
"A fool of a Jedi once said "If you strike me down, I shall become more powerful than you could possibly imagine." That foolish Jedi has not anticipated this."
He extracted a number of pieces of machinery from his cloak and assembled them into a gun-like device.
"This is called the Ysataniri. It fires a tiny capsule based on the Church's Ysalamiri Grenade, which detonates via a remote-controlled explosion, also activated from the device itself. When the capsule explodes, it neutralises the Force in the immediate twenty feet of the area, for twenty minutes. For living Force-sensitives caught in the blast, it is debilitating. For Force ghosts, it is destructive. Since they have no body to continue to exist in, they are sent to the Netherworld of the Force. With our compliments."
Serratus disassembled the Ysataniri once more and stowed the pieces back in his cloak.
"Although I doubt Darth Duff could defeat all four of us in Force-combat, even if he could, I fire the Ysataniri, he's gone for good. The only reason that Dorian and Tao didn't do it while they were on Korriban is because it's Duff. First of all, since he's a dark sider, he'll be sent to Chaos, so we do him the common courtesy of keeping him earthbound. Second of all, he was an amazing Sith and he could still have great unknown wisdom to impart. Third of all, he only killed Eclectus, who's on trial for Insurrection, a penalty for which he probably would have gotten executed anyway. Fourth of all, he's only just regained consciousness, he could be confused. If we can calm him down, he could be very beneficial to the Temple, he may even become a mentor to the Korriban Sith. This is why he is not already swirling through the eternal pain of Chaos with Sidious and Bane. Not because he is too powerful, but because he is too valuable."
When they reached the door to Aequitas's office, Serratus opened it and lead the other two in.
"M'lord, the Shadow Protector has arrived."
If you see dreadlocks and a staff coming towards you very rapidly, you're in trouble.
