From Halopedia, the Halo wiki
A saga wall is a stone mural of chiseled poetic stanzas found in the keeps of Sangheili clans. A family's saga wall commemorates the historical actions, sacrifices and legacies of its family's members. Generally, a keep's poet is tasked with adding lines onto the family saga. Sangheili warriors strive to preserve the history of their lineage and the stories of their victories, so that they may be recited for generations to come.
Battle of Installation 04
Kaidon Ther 'Vadam had his life story carved onto Vadam keep's saga wall. According to the Vadam saga, Ther lost a war with one of Vadam's rivals and was imprisoned. Many of Ther's brethren committed suicide in order to keep what was left of their honor. Ther eventually managed to escape and later recruited followers from the wilderness. With his new allies he returned and attacked the keep, killing all his usurpers. He then threw their bodies into the river, which legend had it ran purple with Sangheili blood for a week. Ther then rebuilt his clan, the legendary House of Vadam.
Following the disappearance of her husband, elder Jul 'Mdama, Raia 'Mdama left Bekan keep with the militant Servants of the Abiding Truth to search for him while they attacked the state of Vadam. Despite the insistence of many male warriors to return home, Raia was determined to storm Vadam keep with them and hopefully find her husband in a dungeon cell. Raia was killed during the Blooding Years by Arbiter Thel 'Vadam's forces. After Raia's death, her eldest son Dural 'Mdama promised he would avenge her and carve her story on their keep's saga wall.
In the original printing of Halo: The Flood, the Saga wall was called a family battle poem.
