What?!, the leader accuses no one in particular.
Who said they no understand plan?!, he says again. His crew look at him oddly but strangely enough begin pointing fingers at each other. Whoever said something, they don't want it to have been them.
This is why me leader. You can't even remember such great plan. This is why he appointed me leader. Me know secret entrance into sewers. Me know how to get into stupid hero hideout. Me know where to get on big metal carriage. They not even notice us. They never notice us. And we use that to advantage, he says, puffing out his chest as he compliments himself.
Me would have been one to blow up carriage if me weren't so valuable to plan. Stupid heroes blow up our black powder at the keep. They not know we have more. They so stupid. Drago was brave soldier, he know how to explode train with powder. Him give life for plan. What any of you done for plan!, he shouts at his crew. They all cower a little at his raised voice.
Nothing. You sit here safe and keep leader company. You lucky I here to protect you. We go now, back to Salar to let him know it done., he adds, hitting one of the underlings over the back of the head.
Move this stuff out, now!
He and his underlings go back to work packing up the stuff they have with them onto these two little carts.
OOC:
The basic gist is they found a way to sneak into the train station and had what amounts to dynamite. They snuck on the car and climbed along it to get to the main train car. They blew open the door and a suicide bomber exploded himself and a few other kobolds strapped with dynamite to take down the train. Inadvertently it caused the rock above the tunnel to collapse in and that made a ramp that launched the train out.
