[Elvia Daily] The Eerie Calm in the Castle Ruins

Objective
Ruben says it's impossible to see due to the green fog blanketing the Castle Ruins, and the eerily quiet atmosphere is giving him the creeps. Let's go patrol around the Castle Ruins in his place.

Dialogue
Ruben Dialogue
There was a fierce battle recently at the Castle Ruins.
It didn't involve the Heidel armed forces,
but some sort of internal conflict within their own...
And now, after that battle, not even a peep.
Could you perhaps check them out and see what they're up to?
Ruben Dialogue (Alt)
Clearly something's afoot...
However, to charge in blindly is an entirely different question...
Ruben Completion
Are you sure? There was no other sign whatsoever?
Then what are they still doing there...?
