In 0 BBY, Heff was killed by the bounty hunterJodo Kast who shot him in the neck with a sennari-poisoned dart. Kast was seeking the Rebel sympathizer Adar Tallon who had been hiding out on the planet for many years. Kast slowly killed off all those that may have been alive when Tallon arrived to ensure they couldn't pass on any information to competing hunters. Upon his death, Tebbi—herself a Rebel sympathizer—shared what she could with a group of Rebels that were also seeking Tallon.[1] After a couple of seasons, she sold Heff's Souvenirs to the SullustanMoplin Jarron.[4]
Heff and his daughter were described in Tatooine Manhunt as "rabbit-like alien[s]". The name "Heff" was later used in the The Starhoppers of Aduba-3 article as an example of a Lepi name, and in this manner his species was revealed.
↑Heff is stated to be a survivor of the "original colony ships", however Tatooine was first colonized in 5,000 BBY. It is more likely Heff is a survivor of the wave of colonists that arrived around 85 BBY. As Lepi lifespan extends to around 100 years, this is the most likely arrival period.
