Houarner was a security officer serving on the USS Enterprise-D by 2370, holding the rank of Ensign. In an alternate timeline where Montgomery Scott rescued James T. Kirk before he could be absorbed into the Nexus, the Enterprise was thrown back in time to 2293 in a universe where the Borg controlled much of the Alpha Quadrant. The Borg Queen possessed the body of Balitor, a Narisian working for the Alliance, and attempted to kill Captain Jean-Luc Picard. Houarner was one of the security officers present, along with Worf and Ensign Porfirio, and helped Worf stun the possessed Balitor when she attacked. (Star Trek novel: Engines of Destiny)

In 2371, Houarner was one of the team assigned to provide security during the inauguration ceremonies for Governor Ra'ch B'ullhy of Damiano and was assigned to the outside of the building with Benesch and Post. (TNG comics: "Perchance to Dream", "By a Sleep to Say We End")
