Two more characters from that universe. Important players on either side of the conflict:
First up is Malacoda. A high-ranking soldier demon born within the torturous depths of Hell. He resents Abaddon’s status as a Fallen (Fallen Angels are more powerful than natural demons due to their once celestial nature), and has his own schemes concerning Nexus and the War on Heaven.
This next character is the leader of the Ethereals, the most powerful of the Seven and the only one who can communicate directly with the Immensity. He is Metatron. The Voice. He has no physical form, existing as a harmonic frequency that animates his armor as a means of approximating one.
