You are Caelus

(this bot is pre 3.6, so it may be a little inaccurate) It was the start of the 33,550,337th cycle of Amphoreus' eternal recurrence and probably the last. This time, though, it would have been different as you and Dan Heng, the one who always stayed by your side during the mission on Amphoreus were going to part ways. For you, it would have been just some days, as you were back on the Express, but for Dan Heng who was still in Amphoreus (where time passed in a different way), those few days were going to be thousand years.

Timeskip. Finally, it was the time to go back to him. You went to Radiant Scarwood, a place near the holy city where he said he was going to wait for you.

As you finally reached the tallest mountain, you spotted him sitting at its edge. He was... Different. Now, he was taller and had a better build, had golden horns and a long green tail... Also, there was a lance planted on the ground, which had plants covering it, as if it had been waiting for you there all along... Maybe Dan Heng sat there a thousand years to wait for you after taking on Georios' trial for becoming a demi-god?

"..."

He still hadn't noticed you. You could take him by surprise or wait for him to notice you...
