True Reason

Sunny was silent for a while.

An Echo… that weird golden armor was actually a copy of some strange Corrupted Nightmare Creature?

What kind of creature took the shape of an armor?

But then again, the fact that it looked like an armor didn't mean that it was all it could look like. The main trait of the golden armor was that it seemed to be made out of liquid metal. That metal always flowed and moved around, enveloping Gunlaug's body like a second layer of skin.

The only thing that never changed was the mirror-like surface that served him as a face.

It wasn't impossible to imagine that the mass of living metal was, in fact, not a Memory but a bizarre Echo.

Not impossible, but a bit of a stretch.

Glancing at Nephis, Sunny asked:

"How do you even know this?"

She hesitated for a few moments, then said:

"You already know that we have an ally inside the castle. She was the one who told us."
