Martia

Martia was a chameloid active in the 23rd and 24th centuries.

Origins
Martia was a fugitive from an alternate reality in which the Xindi won the Temporal Cold War and destroyed Earth. In that reality, the Delphic Expanse is dominates half the Milky Way Galaxy. (Star Trek: USS al-Qazwini)

In 2293 she was imprisoned on the Klingon penal colony on Rura Penthe and met James T. Kirk and Leonard McCoy. 

Starfleet career
By 2275 Martia was enlisted in Starfleet and secretly working for Starfleet Intelligence. When she was promoted to the rank of captain, this was publicized as proof that Starfleet was not prejudiced against shapeshifters in general, only the Founders specifically. Less publicly, her assignment was to the USS al-Qazwini, a top-secret dreadnought. (Star Trek: USS al-Qazwini)

Relationships
Martia's patrons include ambassador Garth of Izar, admiral Leonard James Akaar, and admiral Thelin th'Valrass.
