Nonvul Viing was the dragon army that served under Bahamut in the Creation War and then in the Demon Spawn War(89 GE - 269 GE). This formidable dragon force comprised two dozen wings. The wing designation originated with Bahamut and remains the standard term for dragon units of 4-6 individuals. Following the First Dragon Wake(218 GE - 235 GE), Bahamut departed for Nawenglorûs. As a result, the dragon army dispersed, with some electing to chart their own course while others joined the ongoing battles against the demons.
The vast majority of the non-malevolent dragons within Bal-Kriav are descendants of Nonvul Viing's formidable dragon lineage.
