Erebos

Apparently, he had once been in Moon's guard as her closest, most trusted bodyguard...and seemingly assassin...She had never mentioned him before he suddenly appeared in Vixen's Clan, but he slipped past Stone's notice and not even Auriga the Scout had seen him on his patrols. Once Stone, the Guard, and closest kin of Moon realized his presence, he rushed at him. They had a short battle until Moon flew between them, begging them to desist. Both loyal to her they obeyed. She explained that Erebos was from her past (the past she doesn't speak of) and no more needed to be said. Both he and Stone seemed to respect the other's position and backed away.

Erebos had no trouble moving into the Demonic Woods. He quickly won the respect from the demon dragons and was even invited to participate in the Underground Fighting Pit but refused. Apparently, he'd always been in love with Moon, even though he'd merely been her subordinate. But she wasn't clueless to his affection and loyalty. Although it may have seemed like she'd taken advantage of his feelings by using him to do her bidding (especially the less than reputable), he didn't mind the least. He'd gladly do anything she requested. He even followed her to her new clan though he had moved up the ranks in his old clan, becoming much greater than a lowly servant and assassin.

He's a shifty fellow and clearly only loyal to Moon, but seems to cause no trouble in Vixen's Clan. He follows Moon's beck and call, but don't expect him to lend you any help. And make sure to never, ever cross Moon--unless you want his eyes on you...which believe me, you don't.
