Their brief stay at the Free Space, which was more of a training and a lecture than relaxation, ended when the two couple left the peaceful forest and went back to the Frozen Keep.
"The humans actually want to reach an inaccessible place beyond the keep. It's actually an old monument that was used to hold my soul. My presence here is what's keeping Riarravar intact and they plan to destroy it and force a way out of here. Of course, if this world starts breaking, there is no way every one of them would survive, however, from their perspective, it's better than staying him for all eternity."
Timos explaining the humans' goal, not hiding from the couple the consequences of freeing the soul.
"Wouldn't you want to be set free?"
Seeing that Timos wasn't that optimistic about being freed, Arthur curiously asked. From how he behaved, it was apparent that the Black Devil was bored of this place and wished to leave.
