Vendor

From Memory Alpha, the free Star Trek reference.

Vendor was the homeworld of the Vendorians. The planet, located near the Romulan Neutral Zone, was quarantined by the Federation during the 23rd century.

Carter Winston's trading vessel crash-landed on Vendor in 2264. He eventually died there in 2265, while under the care of a Vendorian who later assumed his identity. (TAS: "The Survivor")
