Tango Kree is the verbal translation of his name in Kosmonik sign language. He is a mid-rank outer hull technician on the vessel Thirteen Cherenkov Blue. Tango is satisfied with his station, but his marriage klatch thinks he is not living up to his potential: He should be a chief inscriber by now! He has a taboo against engineering work ever since he saw a sign written in the cosmic dust scouring of the surface runes.
