Villera'trel was a settlement on the planet Romulus.
In 2381, the Reunification Movement was legitimized by Praetor Tal'Aura's government, allowing them to hold peaceful public dialogues without repercussions from the Romulan Star Empire. This allowed large number of Romulans to attend venues at settlements such as Villera'trel, as well as Rateg, Dinalla, and Ra'tleihfi. (ST - Typhon Pact novel: Rough Beasts of Empire)
