Martyr
The once-mighty Thallonian Empire has collapsed, sparking unrest throughout the entire sector. As rival powers plot to fill the void, the Excalibur is sent out to assess the situation and provide humanitarian aid. It`s a volatile mission for an untried crew--and a mysterious stowaway may end the voyage before it begins.

1. \Mar"tyr\, n. [AS., from L. martyr, Gr. ma`rtyr, ma`rtys,
   prop., a witness; cf. Skr. sm[.r] to remember, E. memory.]
   1. One who, by his death, bears witness to the truth of the
      gospel; one who is put to death for his religion; as,
      Stephen was the first Christian martyr. --Chaucer.
            To be a martyr, signifies only to witness the truth
            of Christ; but the witnessing of the truth was then
            so generally attended with persecution, that
            martyrdom now signifies not only to witness, but to
            witness by death                      --South.
   2. Hence, one who sacrifices his life, his station, or what
      is of great value to him, for the sake of principle, or to
      sustain a cause.
            Then if thou fall'st, O Cromwell, Thou fall'st a
            blessed martyr !                      --Shak.
   

2. \Mar"tyr\, v. t. [imp. & p. p. {Martyred}; p. pr. & vb.
   n. {Martyring}.]
   1. To put to death for adhering to some belief, esp.
      Christianity; to sacrifice on account of faith or
      profession. --Bp. Pearson.
   2. To persecute; to torment; to torture. --Chaucer.
            The lovely Amoret, whose gentle heart Thou martyrest
            with sorrow and with smart.           --Spenser.
            Racked with sciatics, martyred with the stone.
                                                  --Pope.
   

one who bears witness of the truth, and suffers death in the cause of Christ (Acts 22:20; Rev. 2:13; 17:6). In this sense Stephen was the first martyr. The Greek word so rendered in all other cases is translated "witness." (1.) In a court of justice (Matt. 18:16; 26:65; Acts 6:13; 7:58; Heb. 10:28; 1 Tim. 5:19). (2.) As of one bearing testimony to the truth of what he has seen or known (Luke 24:48; Acts 1:8, 22; Rom. 1:9; 1 Thess. 2:5, 10; 1 John 1:2).
