Gren Orchid
Gren was the last to enter through the portal, debating if he should leave behind The God Eater. One should never go into these situations unprepared, but as far as survival went he knew that he would be too reliant on his weapon. This class was suppose to teach him how to survive in some of the most extreme conditions, one which may include being defenseless. Still he took his weapon with him: if he truly had to learn how to survive without it, than the teacher and nature itself will have to learn how to take it away from him. Once the second-to-last student went Gren barrled forward into the teleporter, appearing on the other side with a thud. As usual he was able to land on his feet, but by the time he appeared the teacher was already started the next part of the lesson. "Damn. I shouldn't have waited so long."
The first task they were given was simple. Gather some wood and make it into a fire. Gren was experienced with making fires, though that was in a more urban environment. The likelihood of him finding tin cans or spent batteries in the forest was slim. Still he could improvise and at worse he'd simply light up some dust from The God Eater.
Gathering the materials was simple enough. He wasn't sure how large of a fire the teacher wanted, but Gren found enough sticks to comfortably keep himself warm, which was to say he found a lot. But he also collected some dry leaves for tinder, and a few familiar flowers. He actually pocketed these flowers so he could drain them of their moisture, and when he'd throw them into the fire later they should help keep the insects away from them. It was no powerful propellant, but if Gren had learned anything about survival in the past it was that Grimm could be killed, but misquotes are much harder to shoot down. As for making the fire itself Gren actually grabbed two fairly large rocks, one smooth and one rough.
"Friction creates the heat, but these plants only need a spark. Let the energy from a mere spark spread to the tinder, and use the friction to spread it's influence." Gren rambled quietly to himself. Once he had his kindling in place Gren began to dash the two stones against one another. His first strike actually produced quite a bit of sparks but nearly cracked the stone he was using as well. He had to be more careful and started to dash them together more gently, creating a smaller but steady shower of sparks. By the time the stones broke apart he had created a few small embers. Than he tossed a few dry leaves on top, which took the embers and turned them into a small fire. After that it was just a matter of adding more leaves and twigs until a steady flame formed. But that wasn't enough for Gren: this fire would last him maybe ten minutes if he just kept putting small twigs and such into it. He needed to add more fuel to keep the flames going. And with that end he went back into the forest to gather large branches, most which where on the ground but a few he was more than willing to break off of trees. he'd put them near his fire to dry them out, adding them to the flames once they were sufficiently ready. That would take some time however, but by the time he returned to his little campfire he had gathered a few nice size tree branches. They were being baked by both the sun and the fire place in preparation of being used as more fuel.
