The Bader are a relatively new civilization in the space-faring community butting heads repeatedly with their Dorset neighbors since developing spaceflight, and spending most of their time colonizing the local systems. Little description is given about their territory, appearance or culture but that they are considered an aggressive species by Federation norms, making their co-existence with the Dorset on Delta Sigma IV all the more unusual.
