The amdusi are sentient humanoid giants with bovine facial features, clawed hands, and ashen skin. They are consummate pacifists, and while they are capable of spaceflight, they have long been hesitant to leave their homeworld Duscias, fearing that travelling beyond their world might lead them into conflicts with other species. They have strong telepathic abilities, which they have used to gently persuade hostile species to stay away from their planet.
The amdusi first made contact with other sentients in 2186 CE, when Alliance patrols discovered Duscias while fleeing from a Reaper attack.
