Lannik was ruled by a hereditary monarchy and was independent of the Galactic Republic.
Unlike most other Republic planets, the considerable natural resources and mineral wealth of Lannik were largely unmined and unexploited, making it a tempting prize for enterprising would-be manipulators such as Red Iaro leader General Zug and corrupt Gran Senators on Malastare such as Aks Moe.
Pugil was a sport popular on Lannik. A local team was the New Osler Flejj Beasts.
The planet was discovered by Duros scouts.
Lannik was discovered by the Galactic Republic sometime between 17,000 BBY and 12,000 BBY. In 11,198 BBY, the planet was a victim of the Twenty-Third Pius Dea Crusade.
It suffered from anti-Republic terrorists known as the Red Iaro until 32 BBY. Under the Galactic Empire and even at the end of the Swarm War, the planet remained isolated.
The planet joined the New Republic sometime between 4 ABY and 7 ABY. It was a New Republic stronghold during the Zsinj and Thrawn campaigns.
Lannik was conquered by the Yuuzhan Vong during their invasion of the galaxy.
