Vega from Centaura is generally based on Portugal. The wiki also shows a strong Portuguese-style naming and language influence, which lines up with that reading.

Why people say Portugal

  • Community discussions commonly map Vega to Portugal.
  • The in-universe language, Vego , is described as similar to European Portuguese, which supports the comparison.
  • The name, culture, and general vibe are also read by fans as Iberian/Peninsular-influenced rather than tied to one exact real country.

Small caveat

Some fan posts describe Vega as a mix, with one thread calling it ā€œFrench- Italian,ā€ but the more consistent answer across sources is Portugal. So the safest short answer is: Vega = Portugal-inspired.
