Arthur, Mithian, and the knights were ready and waiting by the time Merlin got back. "Here Merlin, take this," said Arthur, tossing Merlin a sword, which Merlin caught.
"Why do I need this?" asked Merlin.
"I- well...I don't want you getting hurt on my watch," replied Arthur gruffly. He looked away, clearing his throat, then said, "All right, everyone, get in formation. Merlin, can you do anything to neutralize the guards?"
"Of course," said Merlin. "While I'm doing this, do you want me to tell you how many men Odin has?"
"Yeah, that would be helpful," said Arthur.
Merlin's eyes flashed gold, and for a few seconds he stared at the tomb. He turned to Arthur and said, "Odin has thirty men with him and ten men as guards, and King Rodor is inside with Odin."
Arthur smirked. "Okay. You take care of the guards, we'll deal with the rest of the men when we get in."
"Right," said Merlin, and he snuck away.
A few stressful minutes later, Merlin came back. "The guards are taken care of," he said.
"Good, let's go," replied Arthur, and the company advanced toward the tomb. Arthur, Merlin, and Mithian were in the front, followed by the knights, with everyone's swords out and ready.
They company advanced as quietly as possible down a corridor towards the center of the tomb. When they reached the central room, they found Odin, surrounded by soldiers, holding a sword to King Rodor's throat.
"Lay down your weapons," said Odin. "Or Rodor dies."
Arthur glanced over at Merlin, who nodded slightly. His eyes flashed gold, and the handle of Odin's sword started glowing red, and Odin dropped it with a cry of pain.
"On me!" yelled Arthur, and he and the knights charged at Odin and his men.
Arthur rushed at Odin, who backed up against a wall, grabbing hold of Rodor and using him as a shield. However, as Arthur watched, Rodor elbowed Odin in the chest, causing him to double over and release Rodor, who moved out of the way. Arthur took advantage of Odin's helplessness and placed his sword point on Odin's heart.
Merlin, who was busy blasting soldiers, looked for a second at Arthur and saw a soldier about to stab Arthur from behind. His eyes flashed gold, and the soldier flew through the air.
Within a few minutes, Merlin and the knights had knocked out or killed all of Odin's soldiers. Odin himself was still standing against the wall, Arthur's sword resting on his heart.
Merlin looked at Arthur's face, which was full of barely-contained rage. Merlin hurried over and placed his hand on Arthur's shoulder.
Arthur swung around, his expression softening when he saw it was Merlin. He lowered his sword, and Odin lunged forward, impaling himself on Arthur's sword.
