NightWing-IceWing War

The dragon world of Pyrrhia was locked in a major war between the NightWings and IceWings. It was started by the NightWings "stealing" Prince Arctic over two thousand years before the events of The Dragonet Prophecy. The truth was that Arctic loved the NightWing Foeslayer and ran away with her. They had most of their battles in the Kingdom of Sand, since it was in the middle of their two territories, but in exchange each of the tribes had to give the SandWing queen gold and gems. This war led to longstanding enmity between the NightWings and the IceWings, as seen when Morrowseer had the IceWing prisoners at Queen Scarlet's Palace all executed.

Background: Foeslayer and Arctic

Foeslayer and Prince Arctic ran off together, leading Queen Diamond to believe the NightWings stole the IceWing animus blood. When Arctic refused to return, the war began.

Darkstalker

Darkstalker's help was sought in this war, and he invented various magical superweapons for use against the IceWings, such as a shield around the kingdom.

Weapons

The IceWings developed several different weapons against the NightWings, including the Great Ice Cliff. The NightWings developed weapons of their own, such as a fireshooting weapon that shot fire twelve times the length of dragon fire. Many of these weapons were never made or used. 

Negotiation

Queen Vigilance and Queen Diamond sent each other angry letters accusing each other of starting the war under the guise of negotiation. After a while, one of the queens would snap, and the war would start again.

Resolution

The NightWings fled into hiding after Darkstalker's imprisonment without any true resolution to the war.
