((Wow, Lenglon.
That's...detailed))
You gather near the villagers, them sharpening their weapons and practicing their shots with their crossbows. Erin bends down and starts drawing a diagram on the floor, while describing her plan to the group. After it is discussed, you tell the villagers and they get to work immediately on the traps. They run out and funneling the road to make it as per Erin's specifications. Nectarius splits them into groups, one looking for dangerous things and the other making the ramp. The first one find some barrels of oil in the village and spill it unto the floor.
It takes around two hours, and the sun has finally set. The villagers are slowly returning to the fortifications; but suddenly, one Evolved falls to the ground, a big, gaping hole in his back filled with a purplish sizzling liquid. The villagers look at his corpse, his mouth gurgling with the same liquid. They run back, screaming, and following them were more balls of purple liquid falling in the sky. One by one, the villagers fall to the ground, melting. Quite a few have already died, and the rest are terrified.
The people on the towers and the barricades shoot at the Thralls, now closing in quickly. They appear to be moving in a group, but not very cohesively. They shamble about, knocking over each other. The villagers and the Aquisitioners took advantage of this, shooting at them and managing to cut down their ranks quickly. The battle is at your side now, your organization beating their uncoordinated shooting and clawing. The villagers cheer at their near-victory.
Suddenly, at the face of victory, a taller looking Thrall steps in and screams. The noise is deafening; many of the villagers collapse on the floor, the Aquisitioners merely put on their helmets and continue on shooting. The Thralls gather around him, raising their bio-guns and aiming at the barricade in unison. They shoot, and the purple liquid dissolves holes in the wall. The tall Thrall screams once more, and many smaller Thralls rush in, armed with scythe-hands or club-fists. They all rush into the holes and slaughter the forward defense, breaking the barriers and ramps. The Aquisitioners are faring better, but not by much. They cut down many, some by sword, other by gun, and the leader simply fights with his hands.
You can see the leader Thrall's face much more clearly now. He looks like Quar! He is much taller than before, with the same sad face he had right before he took his life. On his head are ten, thin knives, stabbed onto his head. His two eyes have been clawed out, now empty holes. His third eye is now completely open, looking violently around to ensure maximum inefficiency from his minions. He looks at the village and screams:
"FATHER! TRAITOR! WHY? WHY DID YOU DO THIS TO MEEEE? WHY DID YOU DO THIS TO BROTHER? WHY DID YOU DO THIS TO OUR HOME? OUR VILLAGE?" He screams loudly, rushing with as much fervor as his minions, slashing those who got in his way, screaming "father" over and over. Behind him is a great rumbling, and soon, the large creature described by the Aquisitioner leader appears. It is like a large, carapaced elephant, with a trunk and two monstrous arms. It rumbles as it moves across, smashing many tiny Thralls beneath his heel.
The barriers are broken and many villagers have already died. The only entrance is being besieged by monstrous nightmares, and the other sides are just cliff-sides. The Aquisitioners have only lost two of their number, both being taken by surprise. What do you do now?
