Nameless Dan Heng, Chrysos Heir who guards the Earth's Coreflame, steadies the world as it falls, and guides all life across the land to a new home beyond. Guided by his conviction to protect, he follows the light of the Coreflame on his quest, shedding old scales and soaring toward the future despite all obstacles.

“As you can see, that transformation was brought about by the power of the Permanence. Though you may have many questions, I'd like to reintroduce myself before I answer them — I am the Guard of the Astral Express, your companion, Dan Heng the Nameless.”

Q1: No matter what, I just want to say: thank you, Dan Heng.
From the moment we set foot on Amphoreus until today, we've ventured further down the path of Trailblaze than ever before. Every Trailblaze with you has taught me so much, and your optimism and self-confidence have given me courage and strength. I believe that we, the Express Crew, will always trailblaze together, in the past, present, and future. So, there's no need for thanks. Our road is still long ahead of us.

Q2: Can you tell me about your encounter with Terravox?
At first, under the fierce assault of the memoria tide, I didn't see Terravox. Instead, a fragment of memory slipped free, allowing me to walk alongside “him” for a brief moment. As I looked through those bygone days, I suddenly realized: the choice has always been in my own hands. Since the past cannot be reclaimed, why not treat it as a guide to make the future brighter? So when I faced Terravox and learned of his past corroded by suffering and his present wishes, my only choice was to move forward, shouldering the responsibility of protection, carrying them towards broader horizons. That, to me, is the Permanence: to trailblaze into the future, endlessly and eternally.

Q3: You seem more cheerful since inheriting the power of the Permanence! Besides that, what other changes have you noticed in yourself?
The biggest change has been my physical form. After resonating with the power of Georios, I seem to have awakened some traits similar to the Mountain Dweller. I'm still getting used to it, like accidentally bumping my dragon horns on doorframes… But these aren't really troubles. There's actually something quite fascinating: under the influence of this power, I can understand the languages of many living beings, from mighty dromas to the tiny nymphs crawling on leaves. Lately, I've been working on compiling all these animal languages into the data bank. Would you be interested in helping out?

Q4: Of course! But can you still do that world-cleansing dragon thing? The Express is almost due for its big cleaning day…
Guess it's been too long since the conductor last straightened you out, huh? Ah, never mind. Water manipulation and shape-shifting are talents I was born with. I've just gained another force to wield, but my true self hasn't changed. I'm still me.
