Denic was a human woman with red hair who was employed at a personally-owned garage located in Jedha City. This occurred several months prior to the Battle of Yavin. There were whispers that she had previously been a smuggler operating within the Corporate Sector. While spending her time on Jedha, she provided information to the Guardians of the Whills, specifically Chirrut Îmwe and Baze Malbus, concerning Imperial supply operations. In return, she received a portion of those supplies. Afterward, the two Guardians successfully persuaded her to pilot a Sentinel-class landing craft that had been stolen, with the purpose of evacuating the inhabitants of the Gimm sisters' orphanage from the moon.
Denic was seen wearing aged Torjeka goggles along with a spacer's jacket, and she was armed with a blaster.
Denic is a character featured in Greg Rucka's 2017 canon novel for young readers, entitled Guardians of the Whills.
