Casimir didn't know who this Moon was, but they sure sounded like a big shot!
Celestial differences aside, he regarded Arche smiling, feline and calculating and reading closely into whatever there was to pick up. Arche seemed the faithful sort, expectations laid before him and spiraling throughout his life so intricately that they were practically woven into him -- it was quite the sight. He might have been a little shortsighted, if Casimir were to judge, but did not dare to voice his views... if only because the other man had potential. True as stone, true as diamonds, potential. Why, it even made the Qun noble smile to behold him. Magic, determination, resilience, all traits and skills admirable in a person.
"You must be so lonely, walking alone in pitch black." Casimir spoke, his voice a coo. "You're too strong, too sweet, to be so kept to yourself... but, to place your faith in so few..."
"..I can offer you boarding, just for free." Not for free. Casimir knew that everything came with a cost, he knew he was not the type to give things out of the purity of his heart, never an act of kindness so wanted by the gods. He wanted to see what Arche could make of it -- could make of himself -- when little bits of pressure were shed one at a time. "Someone like you, you can't just wander aimlessly, you can't just suffer in silence and wait. Won't you take my proposal? You can have a bed and food for as long as you want to... besides, most troubles roll off my back like water off a duck's coat. Worry not about your own here."
