Dalmari

The Dalmari were the native species of Destination.

After a human colony ship had crashed on their planet, the Dalmari came into conflict with the colonists. They view the colonists as invaders, fighting a destructive war against them. Trapped on the planet, the Master provoked an arms race between the humans and the Dalmari, covertly supplying them with weapons on par with the humans' own.

When the First Doctor arrived on the planet, he tried to open relations between the two races before the Master sparked another war, his server robots killing anyone who attempted a diplomatic resolution. Twelve years afterwards, when the Master had fled in the Doctor's TARDIS, the stranded Doctor revealed the Master's machinations to the planet and spent the next two years overseeing a peaceful co-existence between human and Dalmari.
