Loque'eque (Star Trek: Refuge)

The Loque'eque were a species that originated in the Delphic Expanse. Several centuries prior to 2153 they lost the ability to reproduce and their species began to die out. In an attempt to save their race from total extinction, the Loque'eque engineered a mutagenic virus which transformed the DNA of other species into their own. The humans saved this species by taking several crminals and injecting them with the formula. Some loque'eque live in enclaves.
