I have occasionally seen a train on the Colossus since that superior arrived... I know it sounds strange, so let me explain. The thing is, that train is Charon's "partner", Other End. Although Other End is huge and looks very cumbersome, it is in fact extremely adorable lively, and stays by Charon's side every day like a loyal dog wagging its tail. I was initially a little skeptical when I heard rumors that Charon hangs out with Other End every day. Now I know that it is true.
Don't let Charon's dashing gentlemanly appearance fool you. He is a natural actor who can deceive anyone who lets their guard down around him. However, if he can be more honest with others, he should be quite popular with the ladies since he is a handsome guy with a cute dog by his side—only if he is more honest and trustworthy.

Are you the one in charge of this Colossus? Excellent! Let me introduce myself: I am the ferryman of evil spirits, the admirer of dreams, the artist of the stage, and the conductor of the train of the dead—Charon!
I like to listen to rock music at the maximum volume so that my friend, Other End, can listen to it too as it speeds through dark tunnels and takes me away from this noisy world. I don't have to think or ask about anything when I am with Other End. It feels like we can travel through time, to the time when we traveled around the continent before the crisis and the time when I researched ancient technology with my friends... Of course! It's the same now. We always bask in the sun on to the lawn outside Undercity when we're tired and go for a drive when we wake up. Occasionally, unexpected animal friends would visit our home to enjoy food and wine with us!
Need not be envious! From today on, you'll also be qualified to... watch from the sidelines! Haha!

Do you think I stand out from my surroundings? No, of course not! I'm a talented performer who can adapt to any stage! If you think time has left its mark on me, I can tell you that everything you see is just an act... Yes, I am one of the last of my ancient bloodline and a relic that doesn't belong to this era. My partner is a train from hell called Other End. It loves to reveal its savage fangs and is irritable and untamable. Initially, it was just a toy that a father brought home on a whim to appease his naughty young son, but the young boy loved it far more than anyone could imagine. He continued to study ancient books and learned about the possibilities presented by ancient technology. He wanted one of the large trains recorded in ancient books, and it would be best if it could speak, dance, sing, and play gateball. Other End was the fruit of his subsequent efforts. They cherished and accompanied each other, but fate never stops playing pranks and enjoys manipulating people...
So? What do you think of my script? Isn't it exciting!

Are you questioning the spirituality of my partner, Other End?! I won't permit such thoughts to appear in such a sacred place like this... I mean next to my only partner, even if you are the leader of the Colossus!
What's the meaning of your sympathetic gaze? Handsome train conductors like me are all peerless and independent! When have you ever seen a ferryman with a large group of companions in myths and legends?
What? You want to go on a ride with me on Other End? I'll naturally agree since you're asking so sincerely! This is my gift to you, so don't laugh!

Do you want to hear about the awakening of Other End? One time, I traveled the continent with my partner and learned a lot about the world. However, my father criticized me a lot after I returned to Old Town. My relationship with my family, who followed the old traditions of nobles, became estranged after that. My father left my mother and me after the Darkover because of my stubbornness. When my mother and I were about to be mobbed by the Eclipsites, Other End gained self-consciousness and saved us, but my mother still died of serious injuries in the end... Therefore, I always lose control of my abilities whenever I think about anything related to my family.
Why am I suddenly so serious? You can just assume that I'm reading a script...
