History
When the Gorn asylum-seeker S'syrixx incorrectly assumed that the mammal-dominated Federation would not allow its reptiloid members to achieve captaincy of a starship, his Gnalish Fejimaera roommate Qur Qontallium sarcastically replied he would discuss that assumption with Captain Sigrengar during the next rendezvous between the Galatea and USS Titan in the Vela OB2 Association or at their homeworld Gnala.
