Luke wondered if that was some sort of trap. The enemy was wide open, so he could use the chance to kill the bastard. While that might make things easier for him, it certainly would give a start to the conflict, and his allies weren't ready yet.
"If you accept it, my army will be on standby and won't do anything. You can even send yours to help the others," The horse-face said.
What would happen if he refused was obvious. He would hide behind his army until his enemies were tired and would come to finish them off. Unlike the others, Luke's army was basically made of low-level skeletons. Those guys were really smart. By tempting Luke like that, he might be killed easily, and he won't have the chance to use Necromancy.
"Don't accept it, Luke," Rina said. "It is obviously a trap."
