Tel'laa'vor was an aristic piece present among the Romulan people.
It was a poem that was composed by Japell who wrote the piece in the earliest points of Romulan expansion which narrated the founding of the Romulan people; from the group that Tellus gathered to their journey across space and their landing on Romulus as well as includes the conquest of Romii.
The Tel'laa'vor is the story of legends; of heroes overcoming adversity, enemies and even nature itself. As such, every Romulan child knows the story that it teaches which has spawned other works of artistic art. The words of the Tel'laa'vor are treated almost as scripture by the Romulan people even though they do not consider it divinely inspired.
