Is It ...?

Richard saw that the surroundings were very messy once and sadistic. This place is filled with shapes close to destruction. The second sun had shattered and Richard saw Kalden. There is nothing left here. Neither the second sun nor the alchemist made it. 

Richard remembered very well that they could get out very quickly if they wanted to, but Kalden restrained them using only the movement of his hand. 

Observing, that's the reason said by Kalden. They obeyed Kalden's wishes. Noting what was happening in front of them, when the alchemists died in front of them, even Kalden did not flinch from his place at all.  

He was still so cold, as always. 

As the Herald's attack rolled very quickly, Kalden was able to dodge, but instead he took them right near the second sun. 

[He did it on purpose..]

Richard thought that way. He considered Kalden to do what Richard wanted, not to let this fall into the hands of their emperor. But it turns out that Kalden's mind is broader.
