Platonius

Platonius was a class M planet, home to the Platonians.

History and specifics[]

Platonius is the fourth planet in the Helios system. (TOS reference: Star Trek Maps, FASA RPG module: The Federation)

Its surface is 75% covered by ocean. Three mountain ranges border its sole continent, which reaches from southern tropics to the northern arctic regions. Its capital city was located near the equator along a sub-tropical coastline reminiscent of Greece.

Deposits of kironide were absorbed by the local plant life. The planet had no indigenous intelligent animal life, only the Platonian colonists. (Decipher RPG module: Worlds)

Worlds reported that it had 0 moons, 1.02 G gravity and 25% land mass. The Federation stated that it had 1 moon, 0.97 G gravity and 50% land mass.

History[]

Circa 100 BCE, Platonius was settled by refugee colonists from Sahndara, who'd previously settled in Greece and come to appreciate the culture and the philosphy of Plato. (TOS episode: "Plato's Stepchildren", Decipher RPG module: Worlds)

In 2268, when the USS Enterprise visited this world, its inhabitants tortured the crew members that beamed down, including Captain James T. Kirk. (TOS episode: "Plato's Stepchildren")

When he was transported downtime from 2270 to 2020 and into Shaun Christopher's body, Kirk hoped Christopher wasn't stuck in the body but powerless because he had learned what that felt like on Platonius and had hated it. (TOS novel: The Rings of Time)

On reference stardate 2/2205.24, the transport USS Zirconian Star noted the theft of a large amount of kironide from Platonius. (FASA RPG module: Star Trek IV Sourcebook Update)

Legacy[]

In 2269, Kirk once dreamed that the palace on Platonius was burning down. (TOS novel: The Three-Minute Universe)

In 2293, Nyota Uhura recalled their imprisonment on Platonius shortly after hearing about Kirk's apparent death aboard the USS Enterprise-B. (TOS - Crucible novel: Provenance of Shadows)
