The Terahnee plague was the plague that swept through Terahnee, helping the relyimah win their freedom. The plague was brought to Terahnee by Atrus and the others who were looking for D'ni survivors. To them it was a harmless stomach bacteria, but it was deadly to the people of Terahnee. Most of them died, but some, like Eedrah Ro'Jethhe, survived. After the plague there were still over 2 billion relyimah alive.
