Trion (species)

The Trions (pronounced "try-ons") are a race of near-Humans from the planet of the same name.

Physical charateristics
They look identical to Humans and can survive in similar conditions.


 * Since the nurse at Turlough's school had no problem when examining Turlough, that would imply that Trions have similar, if not identical, internal structure to Humans. (DW: Mawdryn Undead) Based on Turlough's comments, he may be older then he looks, implying a different rate of aging. (DW: Terminus)

History
Prior to Turlough's time, Trion was invaded by the Tractators, an experience so horrific that for generations to come, an ancestral memory of it would be triggered at the sight of one. In the case of Turlough this caused abject panic and fear. (DW: Frontios).

The Trions are a reasonably advanced species, having space-faring capabilities and energy weapons. One Trion seemed completely unfazed by the fact that the Doctor's TARDIS had a transcendentally dimensional interior. (DW: Planet of Fire) Turlough had familarity with transmats. (DW: Mawdryn Undead)

Trion society was for a long time constituted almost as a caste system, with much of the power and privilege the sole preserve of the ruling Clans. Turlough and his family were members of one of these Clans.

The Trions had colonies and representatives on many planets, including Earth, where Turlough's exile took place (DW: Mawdryn Undead), Sarn, Darvey and Verdon). Despite this, many of these colonies were poorly maintained or forgotten, such as in the case of Sarn. (DW: Planet of Fire)

During Turlough's youth there was an uprising against the Clans, led by Rehtcaht. The Clansmen were deposed, their families broken up and sent to many other planets - some Trion colonies, some not. These political exiles were marked with the Misos triangle and were watched over by the Custodians. Rehctaht's tyrannical regime was eventually overthrown and the exiled Clansmen were allowed back to their original home. (DW: Planet of Fire, TC: Turlough and the Earthlink Dilemma)
