Dann, a male human from the planet Akiva, born to Senator Pima Drolley, who served as their homeworld's representative in the Galactic Senate of the New Republic. In the year 5 ABY, Dann, along with his sister Merra and their mother, journeyed to Nakadia because the planet was chosen to be the new location of the Senate for the upcoming year. While there, the brother and sister noticed Sinjir Rath Velus, a former Imperial Loyalty officer, standing outside Izzik's restaurant located in the capital city of Quarrow. Because Velus had been significant in the liberation of Akiva, the two kids requested that he come and meet their mother. However, Velus, who was preoccupied with spying on Senator Ashmin Ek, declined their request and told them to leave him alone. The siblings, disheartened, persisted in attempting to convince him, but Velus, realizing that they had caused him to lose sight of his target, insulted Dann and then quickly left to locate Ek.
The novel Aftermath: Empire's End, penned by Chuck Wendig in 2017, marks the initial appearance of Dann.
