Which sounds better for the possessive for of Taurus?
I am writing a sci-fi series set several thousand years in the future. I have a group of humans from Taurus Prime. At one point, nearly 5000 years ago, they were independent from the Earth Republic. What sounds like a better possessive form for someone from that world or referring to it (e.g. architecture)?
Tauri
Taurean
Taurusian
