House Lannister
House Lannister of Casterly Rock is one of the Great Houses of Centros, and the largest house in the Westerlands. It is among the richest and most powerful houses. The Lannisters are renowned for their blonde hair and unique soldier uniforms. With 30 expendable minifigures, the Lannisters possess the largest army in Centros.
The Lannisters rule over the Westerlands. Their seat is Casterly Rock, a large rocky cliff with habitations and fortifications, practically regarded as a city. Their capital however, is Lannisport, a city to the south of Casterly Rock. Lannisport also serves as the capital of the Westerlands. The head Lannister is named Warden in the West. The person ruling over Casterly Rock is titled the Lord of Casterly Rock. For Lannisport the title is Lord of Lannisport. Though their official words are "Hear Me Roar!", the unofficial motto, "A Lannister always pays his debts" is used much more.
History
Tytos's Demise
For a few decades, Tytos Lannister ruled over the Westerlands. He was widely seen as weak and not taken seriously by his vassals. Two houses in particular, House Reyne and House Tarbeck, openly rebelled against Tytos. Though Tytos demanded they pay tribute and remain loyal, Reyne and Tarbeck both declined. Tytos declared them in open rebellion and called his banners. In the first battle, Tytos was assassinated, making Tywin, his eldest son, the new head of the Lannisters. He continued Tytos's war and besieged Castamere and Tarbeck Hall, killing all family members of House Reyne and Tarbeck. He replaced the now-extinct houses with House Wynch, a local house that supported the Lannisters against the Houses Reyne and Tarbeck.
Tywin's Rise
After Tywin defeated houses Reyne and Tarbeck and had all their family members executed, the Lannisters were respected more. Tywin united the armies of the vassal-houses, forming one large Lannister army. Though still outnumbered to several other houses, the Lannisters grew to become one of the most powerful houses.
Robert's Kingdom
Robert Baratheon, the lord of the Stormlands, requested the lords of all eight Great Houses to visit Stormshaven to discuss unifying all houses as one kingdom. All eight houses, including House Lannister, accepted. Tywin represented the Lannisters in the meetings. In the meetings, Tywin spearheaded the ideas to allow the houses Langton, Jorgensen, Harren and Bolton independence. Though the Tyrells already had made plans to release Langton and Jorgensen, the Harrens and Boltons appreciated the Lannisters's ideas.
In one crucial meeting, the royal family was chosen. Due to house Harren and Bolton being independent because of the Lannister effort, they voted for House Lannister. However, it was not enough for House Lannister to become the royal family, though this was not Tywin's goal either, as it was not plausible. The Jorgensens received one vote from the Baratheons, the Lannisters two, from the Harrens and Boltons, the Tyrells received three, from the Jorgensens, Langtons and Martells and the Baratheons received six, from the Starks, Lannisters, Tyrells, Tullys, Ormeres and Arryns. Soon after, the Kingdom of Centros was officially established. Jon Arryn was named Hand of the King to Robert, though Tywin was the third option after Jon Arryn and Eddard Stark.
Post Establishment
Shortly after the establishment of the Kingdom, the great houses attempted to seduce Robert Baratheon with a queen. Tywin Lannister did so as well, offering his daughter, Cersei Lannister. Jon Arryn advised Robert to marry Cersei, making Cersei the queen of the kingdom. She proceeded to have four children, named Baratheon, but secretly fathered by Jaime Lannister, Cersei's twin brother.
