Huh, the guy wasn't a Mundane if he was so accepting of demons. Not a Shadowhunter. He knew too much about magic to be someone with just the Sight. Downworlder? Warlock without an obvious mark? "I don't know if demon energy feels different when it's used to power a vehicle. I never tinkered with them except when we spiked the gas tanks."

"Different realities, different magic." Giving the bike another wistful look, Alec focused on the owner instead. "Are you a warlock?" It wasn't a tactful question but better to ask than to screw up and say something stupid. "Vampires back home have bikes that run on demon energy. My parabatai stole one but he never let me ride it. I wasn't going to risk starting a war over a motorcycle."
