During the Fourth Medieval Era, year 429, Luapo wanted more territory, and most of all more wealth.
They turned to Švinfure to join them. When Švinfure declined Luapo declared war, with King Naao leading. The Švinfure locked themselves in the mountain range. They had full protection, and full artillery. When Luapo attacked, they were always met by an overwhelming force of objects thrown, hailed and chucked at them.
Luapo attacked four times before they gave up. The war ended with nothing but Luapo being humiliated.
