Garissa

Garissa is a formerly terracompatible planet, which until 2581 harboured a florishing Kenyan-ethnic world.

Pre-Genocide Garissa
Garissan culture was deeply influenced by the Legio Maria Church.

Genocide
Following a dispute over the ownership of the Dorados, Garissa was envolved in a war against Omuta in 2580.

In 2581, Omuta deployed antimatter planetbuster bombs against Garissa, massacring most of the planet’s population, and rendering the planet uninhabitable.

The surviving Garissans were given settlement rights over the Dorados as war crimes compensation.

Legio Maria actually exists, a schismatic Christian denomination stemming from the Roman Catholic Church and based among the Luo people of East Africa; tNA words it "Maria Legio Church". (The similarly named Catholic laity organization Legio Mariae / Legion of Mary is a different, unrelated entity.)
