The Intarsa League represented a criminal syndicate that functioned within the Cularin system as the Galactic Republic neared its end.
The Human Dersa Welles headed the Intarsa League, who made their appearance in the Cularin system circa 31 BBY. Following a short period of activity in the system's outer territories, they determined that they were no match for the numerous pirate gangs operating from the Cularin asteroid belt. Consequently, the League moved to Tolea Biqua, a city located on the planet Genarius. Once there, they initiated various fraudulent schemes in Tolea Biqua and in Bayonard, a platform city situated on the neighboring planet Cularin. However, a competing criminal group launched an assault on the League, resulting in their shuttle crashing onto the property of Cularin's Blue Star Centre. Seeking shelter, the League members occupied the building and took the people inside hostage. Welles stipulated that the faction responsible for attacking the Intarsa League must be arrested, and that the League should receive a starship, 10,000 credits, and the freedom to exit the center without facing any interference. Ultimately, the Office of Peace and Security mounted an attack on the center, engaging and overcoming the League in combat.
