Desonis is a seaside kingdom of Terandria.
The kingdom has several port cities.
During the Second Antinium War that took place in Izril, the [Necromancer] Az’kerash suddenly turned against Desonis with a massive army of Undead. He quickly overwhelmed the kingdom’s army but did not approach the capital. Rather, he seized a local port and set sail towards Northern Izril, where he marched south towards Liscor.
