Her  family is an old Longbeard family originally from Erebor (the Lonely  Mountain) who sought refuge in in the Iron Hills during the rein of  Smaug the Terrible. Zindri was born at the end of the Winter of TA 2877.  She became a traveling merchant of her crystal jewelry at age 50; her twin brother Svior coming with her as an escort and fellow merchant. She was in Ered Luin (the Blue Mountains) when she got word that her homeland was reclaimed, but in doing so, it had claimed her father's life. Her mother wrote begging her children to come home. Zin heeds her mother's words, hurrying towards home with a pony with part of her jewelry stock still packed on it, and leaves her brother behind with the  rest of their wares.

Right before making it to Bree, the  pony with her wares spooked and ran. She is hoping to either find word about it or work to make up what she has lost, as her coin purse is not heavy enough for her to make it all the way home.

Her axes are made by her father and are very important to her, especially with word that he has met his end. He was the one to teach her and her brother how to properly use an axe, though she hasn't needed to use this skill much. Her secondary name is an honor to her craft, carving crystals into pretty jewelry and trinkets.
