House Slagathor - Song of Ice and Fire
Maira River is a small river that runs from the Black Hills to Frederic Bay. It is not a very dangerous river, but it does make the grasslands a bit salty – Maesters aren’t quite sure where the salt comes from, as the water is freshwater. Regardless, it makes the local sheep particularly tasty.
Maira River is named after the daughter of Felix Slagathor who died the night before she was to be wedded. Family legend says that on her deathbed Maira said if she could not marry her love, she then wished to be named after the local river that ran from her love’s lands to her family’s lands.
Previously, the river was called Esthere Little River, named by House Grafton before the Targayen Invasion. But really, Slagathor did them a favor. Esthere? Awful!
