Ereuvir's eyebrows raise slightly at that, but it's more playful than a real surprise,

"Anything?" the tone is almost purred, a bit too intent for the rest of the conversation. It is, in some ways, what he's been waiting for, and the anticipation of it colors his voice. "Would you truly?" He doesn't actually doubt Arkady's devotion, he more just wants to hear him say it, wants to see what he looks like when he fully realizes what Ereuvir is offering. He takes a sip of his wine, lets his lips curl back into a grin,

"And if I said that I knew where he was, that such a thing was possible? Would you walk straight into the Underworld, knowing that you might be tortured there alive? The only people who leave the Underworld after they set foot on it's soil do so at my pleasure. Your magic will not help you there." For someone else, that might sound sinister and perhaps it does a bit here as well, but the tone settles more firmly into seduction rather than an attempt to frighten.
