Three Planets

Galaxy Portal

Space Marines Portal Ultramarines

The Three Planets are part of the Ultramarines realm of Ultramar. The planets are Masali, Tarentus and Quintarn. They are three small planets forming a triple world combination, orbiting around a common centre of gravity.^[1]

Each is an arid desert agri world with giant horticultural cities. Their cities are enclosed by giant domes; within flourish lush forests and gardens.^[2]

The worlds were invaded by Orks just after the battle with Hive Fleet Behemoth but were then liberated by Marneus Calgar.^[2]
