Olympian Army fighting Typhon.
The Olympian Army was a coalition of Greek Gods, Roman Gods, demigods, and various other forces on behalf of Mount Olympus in the early 21st century. The army engaged in the brutal Second Titan War, Second Giant War, Great Imperial War, and Second Demigod Civil War. Often, the Olympian Army fought against other demigods or monsters who were fighting on behalf of the Titan Army or Giant Army.
After the Second Giant War, the Olympian Army de facto dispersed as Zeus turned on Apollo, effectively breaking the coalition. The Triumvirate Holdings managed to rise to prominence after the dissolution of the army.
