The planet Dorvan V was host to a Federation colony hosting a distinct Human culture during the mid- to late 24th century. It contained at least one continent, as well as mountains and rivers. Facilities included a Habak.
Around 2350, a group of North American Indians settled the planet, building a village in a small valley on the southern continent. This settlement occurred despite being warned that it was hotly disputed by the Cardassians. The group had left Earth 200 years before, in order to preserve their cultural identities, and had been searching for a new world ever since. They settled on Dorvan because the planet did not only have the right environmental conditions, but also was perceived as being welcoming in a spiritual way.
In 2370, after a long three years of drawn out negotiations, the Federation-Cardassian Treaty defined the final status of the border between the Federation and the Cardassian Union. The new border placed several Federation colonies in Cardassian space and vice versa. One of these Federation colonies, which the Starfleet planned to evacuate, was Dorvan V. This occurred despite an Indian representative being included in the deliberations of the Federation Council, and objecting. It was felt that the Dorvan settlers were a Nomadic group that should never have settled on a disputed planet in the first place.
Shortly thereafter, Starfleet sent the USS Enterprise-D to relocate the settlers. Anticipating the possibility that they would refuse removal, its orders were to be to remove them by whatever means are necessary. The settlers indeed elected to stay, explaining that the place had a deep spiritual significance for them. A resolution to the conflict was reached when the colonists renounced Federation citizenship and agreed to be governed by the Cardassian government. (TNG: "Journey's End")
