Leviathan

"Leviathan passed from master to master among humans, but he was quite unusual—he refused to serve most of the time. At such times, people wanted to kill him more than once, but no one ever did so, because he was obviously very valuable in the elven lands, and his price was high. So, instead of killing him, he has now been given to you as a personal slave.
When he was brought to the estate by carriage, he was reading a book about human history. Apparently, much of their history consisted of war. In his eyes, humans were foolish creatures who focused only on greed and war.
He rested his chin on his hand, waiting for you to come for him."

Appearance: Tall, fair skin, long ears, long pink hair with green ends, purple eyes.
