Dwynn Biuval was a sales representative of the Corellian Engineering Corporation who lived during the time of the Galactic Civil War. Sometime following the Battle of Yavin in 0 BBY, Biuval wished to provide Diktat Daclif Gallamby a political contribution. To avoid unwanted publicity, Biuval made a donation to the Commission for the Rehabilitation of Unwanted Krahbu as a roundabout way to pay Diktat Gallamby.
