When Harold shook him awake, Nicolaos had but vague memories of a somewhat unpleasant dream. His mother had been in that dream, and that couldn't be good. It put him in an irritated mood.
The sun was still down, and it wouldn't be up for a while yet. Nicolaos calculated that the night guards would be getting tired soon, the perfect time to suprise them would be an hour or two from now. He didn't know how long the tunnel would turn out to be, so he figured they'd better get going.
"Alright, let's get going. Since the entrance was blocked, I doubt they have guards on this end of the tunnel, so it should be safe to light a few torches." He was already rummaging his pack for one. "Listen carefully, I'll explain my plan as we walk." He found a torch and lifted it up, then flicked a finger at it. Crackling sparks of energy emerged from his finger and lighted the pitched cloth.
He led the way into the tunnel. This part was obviously manmade, the shape was mostly symmetric and there were wooden, well preserved supports at regular intervals. The air was dry and without any suspicious odours. However, the further in they went, the colder it became.
"First of all, we need to find the guards before they find us. Be wary of any traps and wards, magical or mundane. There probably aren't many of those, since this tunnel is supposed to be used by the defenders, not us, but you can never be too careful." His own eyes were constantly scanning the surroundings, especially in front of his feet. He didn't look at the people whom he was talking to. "I'm also thinking of sending Jimmy to scout ahead." The assassin could use ki to enhance his senses, and thus move outside the torchlight's range, though it would be dangerous.
"Once we do find the guards, our primary plan is to attempt to kill them before they can trigger any defence mechanisms. We'll need bows and magic. Acan targets the mage, of course, if there is one. Estia, an explosive fire enchantment on your arrow, please. Fiona, you take care of anyone reaching for a switch or anything else that looks like a trigger. I can shoot an energy arrow, but only once, I can't cast that spell in rapid succession. Nex, you're our last resort. Hopefully you won't have to do anything, but be ready for anything. If they manage to trigger a collapse, we may need some heavy magic."
"If we fail, we'll try try to get out of the way when the tunnel collapses, and once it calms down, Harold will dig us through. Any questions or suggestions?" He finally looked over his shoulder as he said these last words.
Right that moment, something clicked under his foot. A few meters further into the tunnel, five bolts shot from the roof, diagonally towards Nicolaos and the people close behind him.
