Tanamar tried to curb his annoyance, but it definitely showed in his voice... "Athena, take a look at its right hand."
His girlfriend leaned forward, as if she was squinting her eyes underneath her helmet... "Is that... a lizard head on its arm?"
Close enough. Old Man Harkus said that he'd built the armor suit's forearm to resemble a dragon's head.
"That..." Tanamar pointed, "is the defining characteristic of Divine Armor Orcus."
He turned to Athena, crossing his arms... "The rest of Tyrion knows it by a different name: The Oathbreaker."
"The OATHBREAKER?! Wait-wait-wait!" Athena cradled her head in her hands-- "That doesn't make any sense! Orcus is supposed to be a Champion of the Flame! AND that's the same as Tancred's gladiator name!"
Tanamar shook his head, "Orcus isn't a person. It's a title."
