Asahf was the leader of a group Arin'Sen refugees who, in 2152, fled from their home planet of Raatooras to escape the oppression of the Klingon Empire.

He and his group were near death when the Enterprise NX-01 found their disabled ship. Captain Jonathan Archer ordered a docking and rescued the alien. Asahf explained that their planet had been annexed by the Klingons, who stole their resources and abandoned them. They decided to escape to freedom, but were pursued by a Klingon ship under the command of Duras. Asahf and his group were saved by Archer - Enterprise disabled the Klingon ship and transported the aliens to safety. (ENT: "Judgment")
