Margrave is a late addition to the family of Human colonies. Discovered in 2427. Kzinti planned an attack on the planet in 2560, but never actually made it. Completely covered with forest. Has Bandersnatchi inhabitants.

In the Ringworld era it is still a frontier world, and is home to enormous birds the inhabitants have dubbed "rocs". It orbits Lambda Serpentis (27 Serpentis), a G0 star 34.7 light-years from Earth. It is named after its discoverer, J. Margrave Julland.

In 2380 it was the closest human colony to the Trinoc worlds.
