Whiforlans, an avian and sentient species originating from the world Whiforla II, who resided on the Shipwrights' Trace hyperspace lane, communicated using Whiforla-song, considered one of the most intricate languages in galactic space. During the year 0 ABY, a Whiforlan rebel group, coupled with various others along the Shipwrights' Trace, managed to eavesdrop on Galactic Empire transmissions. Consequently, the Rebel Alliance dispatched Luke Skywalker to connect with these rebel leaders and obtain data-tapes holding the intercepted logs, with the hope that they would provide the Rebellion with insight into Imperial activities throughout the entire hyperspace lane.
