The Mysterious Enemy

The Deities were enraged. The demons had crossed all limits.

Without wasting any more time they headed with their army of 900,000 guards straight to the Demon Realm. 

Whoever was this new enemy, they were really intelligent. To keep the Demons occupied until the Deities reached there, another group of assassins had attacked the demon realm.

The Deities were so enraged that they didn't give any chance to the Demons to prepare for the war and attacked their realm in the middle of the night.

Since, both the princes were in Southern Province of the Demon Realm, the Northern Province was left unprotected and faced most of the wrath of the Deities.

Because of the peace treaty, the demons had pulled their guards down. None of them were prepared for a sudden attack. Especially when there wasn't one but two completely different groups of attackers.
