Jinx cursed as she climbed out of the air duct, wincing at the amount of dust that covered her.
Looking at Long Range, she shook her head, "Nothing in there. I hope that means we got them all."
The sniper frowned, looking up at the ceiling, "Are you sure you went through all of them Jinx?"
She growled, "Yes, I'm sure! I crawled through every freaking air duct on this side of the base! I checked in at every single vent I could find and I can verify that there isn't a single soul box in any of them!"
Long Range pointed upwards, "I never saw you check in at that one."
Blinking, Jinx looked up as well at the vent he'd indicated. Frowning, she mentally rechecked the duct layout for the area they were in and told him, "I don't know that one..."
Looking at each other, they made a quick decision. Long Range cupped his hands in front of himself to give her a boosting step, which Jinx quickly used to stand on his shoulders. Reaching up, she carefully ran her fingers over the grating and found the hidden screws.
It was quick work to undo them with one of her thinner throwing blades and soon she had the vent cover off. Checking carefully for traps, Jinx grabbed the sides of the vent and pulled herself up.
Almost as soon as she did, one of those horrible dark gray boxes was before her eyes, making the female vampire blanch. She quickly looked at the walls of this little hiding place and swore. Lowering herself carefully, she stood on Long Range's shoulders for just a second longer before quickly climbing off him, "We've got one! Firefly must have either built an additional section of air duct himself or he sealed a part off and never thought to add it to the base plans."
Long Range swore himself, "We'll need to inform the team. Are you comfortable with removing one of those boxes?"
Handling a soul box was tricky, but Jinx still nodded, "I'll be fine. It'll be hard to get it down but I should be able to manage it."
He nodded to her, raising his gauntlet to inform the team. As he did that, Jinx cast her gaze upwards again and shuddered.
Soul boxes were normally heavily inscribed on all surfaces so as to help keep the demon's soul imprisoned. But the boxes that Firefly had hidden throughout the base had had many of their inscriptions removed, leaving them as dangerous traps for anyone that touched one accidentally.
The sooner they got that thing re-inscribed and out of the base, the better.
