Mephis stared at Red with brooding eyes. Did she really stick a sword into his chest? How bold of her to even do such a thing. Anyways, the Darkling will want her alive, so killing her right now wouldn't be a good idea – even if he wants to.
The tale of Mephis being a Harbinger of Death and people and faeys dying when they see him was actually a lie. They didn't die because they just looked into his fiery eyeballs. They died because Mephis killed them with his own hands.
He wasn't particularly fond of being looked at straight in the eyes. It was rather a quirky insecurity for a daemon such as him with great powers. Powers that were more than just average and far surpasses even High Magic of any Faey Court.
The daemon had to give it to Red though. She was really something. The halfling may have been part human who didn't know of her powers for a long time, but she was able to capture Mephis with just one strong spell.
