Kaiden would have called it a corridor if it was entirely man made, but the wall to their left was nothing but carved rock with noticably bloated contraptions attached to pistons that shot into the rock itself. Had they been moving it would have likely been too loud to speak, but in the dimness of the underground every footstep was heard. The metal grating beneath their feet squealed or simply reverberated their steps. 

Sabatine and Kaiden were at the front, pistols out and held before them, arms not too rigid with their right hands holding the grip and their left hands keeping the gun steady for any chance they might need to fire. Kaiden hadn't fully been trained for something like this, but he had enough training in tangentially related areas to at least show some semblance of professionalism. Sabatine as well, he noted. He'd always been a bit jealous of her work ethic. He might have overcome certain expectations of nobility, but at the end of the day he still felt lazy in some areas. Behind them, the others stalked as quietly as they would, though Kaiden did hear a small bump and a light smack from someone behind them. He gave a closed mouth grin, judging who might have done the tripping. Considering how long the hallway was, if that was the only overt noise they made, they were doing well so far. 

The mountain route abruptly turned, logically in Kaiden's mind, if where they were underground was where he believed them to be. The tunnel had made a straight shot at a 45 degree angle away from the manor, so now it fed completely back in a sharp turn. The amount of precious gas was so plentiful it likely covered the entirety of the mountain. No wonder these roughshot backwater nobles were so rich. 

Glinting ahead, Kaiden and Sabatine could spot the first real lightsource before them. In unison they held their hands up to halt the others behind them. The others stopped, and the two of them stalked forward silently, taking the safety off their pistols. Kaiden didn't look back, because if he did Tilda would likely have taken that as a sign to follow and that was the last thing Kaiden wanted. Inch by inch, they made it to the end of the walkway where an arch fed into a small, underground compound with three concentrated light sources. Mundane lamps, evidently. 

Sabatine had a better vantage point being on Kaiden's left, and she leaned into the hallway for a fraction of a second. Then she waved three signs to Kaiden, the prince recognizing them immediately as the NAVO hand language they had learned together on their third date. It took them all night to poor over the military signals and practice them over a bottle of vodka, but they'd gotten quite good and used it as a playful joke until their break up. 

"Four men...assault rifles...playing cards" her sign said, before she gave a waving motion with her hand indicating she would move in while Kaiden flanked them. 

"Hello no," Kaiden signed, his ring and pinky finger splayed out before his thumb lifted as well. 

"No grenades." Was her next sign, and he rolled his eyes. He never suggested that! 

"No...splitting up...you take right side of door...I take left. Two men each." He signed. She hesitated, but then nodded.
