Dunari was a Human male entrepreneur who was an old friend of Tomaas Azzameen and the founder and owner of Dunari's Rest Casino during the Galactic Civil War. He was also the leader of a powerful and large trading coalition based in the Outer Rim Territories, mainly the Mayagil sector.
It was known that he and Tomaas used to make Kessel Runs with Imperials in Hot Pursuit. What they both lacked in finesse they made up with luck. He had his own Muurian transport called Deadman's Hand.
After the Galactic Empire/Legends destroyed the Rebels' main supply center on Gal Milnor late in the war, the Rebel Alliance was in dire need of resources and supplies and call on Dunari and his coalition to provide them, a call he accepted.
In his personal SoroSuub Personal Luxury Yacht 3000 Raw Deal with the Rebel Alliance who had sent a Muurian transport Saloon, he negotiated a deal for his trading coalition to secretly supply the Rebels for their attack on the Second Death Star at Endor. But he didn't expect the Hurrim, lead by Golov Nakhym, to betray them at the Nezni system by firing on innocent civilians. Dunari then removed the Hurrim from his coalition and placed bounties on their heads.
Soon Dunari's casino was attacked by Imperials tipped of by the Hurrim. But the attack was repelled and Dunari was able to get the guests and the personnel, along with Emon out of the casino and into safety.
Fed up with the Hurrim, the Alliance and Dunari's forces launched a full-scale assault on the Hurrim's nearby asteroid base, rescuing Dunari's men and destroying the station, while capturing the notorious Golov Nakhym.
