Envy's eyes shifted without focused, the clouded orbs darting around Kire as he took in the words and considered their introductions. Gavin, he zeroed in on when he uttered the sound, but Rab's 'voice' was harder to pinpoint. 
"Gavin the Gemini. And Rab, a half-Kartaian." He tilted his head slightly, as if still struggling to locate the half-elf. Rab shuffled, either in anxiety or because he realized this, and Envy zeroed in on him at the sound of his feet on the soil. 

"You cannot speak. May I intrude into your personal history and ask why? If anyone knows, I mean."
Rab quickly turned to Kire and Gavin and opened his mouth, pointing to the stub of his severed tongue. Behind Envy, Aeron made a face. 
"I see. Well," Envy smirked, shrugging, when the answer was relayed. "I do not see, actually, I believe you've realized. So I think the two of us would make quite the pair." He smiled, and Rab inhaled, chest swelling. 
Then his face turned toward Gavin. He hoped. "And you, Gemini. Under the influence of dark magic, but escaped from it I presume in the nick of time to help our dear heroes in their time of need?" Envy grinned, showing his pointed teeth. "Sounds very convenient."

Envy let the tense silence fall for little more than half a second before he shrugged. "I don't believe so. If you were brought here, you're trusted enough. Plus there are several people here to whose bad side not even I would venture. One of them [i]apparently[/i] punches trees to lumber in her spare time." He cast a (nearly) pointed glance in Kire's direction. 

"You both may stay here, yes. Until such times as you decide to venture on, if you decide to do so. But I warn you, we are not strapped for supplies and comfort, though efforts have been made to rectify that. And you will both be put to work. Is that understood? Do say yes in some vocal fashion, as I cannot see you nod, young man." He grinned more kindly still towards Gavin as he stood sheepishly beside Kire. Rab smacked his lips together in affirmative.
