((Teleporting to the moon would instantly kill you, the near-vacuum ripping your body to shreds))
As Lothian touched Titan.... something was wrong. Instead of disappearing, Lothian found himself still in place, runes on Titan's back glowing up. In the moment of confusion that followed, Titan grabbed Lothian by the neck. The man had tried to use magic on him. Luckily, he was almost completely magic immune due to his anti-magic barrier. Titan held the being - probably a human - in the air, and knew he could break his neck just by squeezing. All that stopped him was the hurried shout from his master. 
"No! Don't kill him! You piece of scrap!" Zargo sighed, looking up at the teleporter, as he hurried over. "I'm terribly sorry, sir. However, you must realize he is a combat golem, and is trained for war. I would advise not attempting to do such a thing again." Zargo considered whether this person would pose a threat. While Zargo disliked the idea of killing this stranger, he wasn't inclined to endanger himself. Titan might be immune to magics such as teleportation, but he was not.
