Idunn is a Coastal Boletus and Ninas cousin but Idunn had a very hard life. In her village they are so superstitious that they believe that those Boletus that are born with golden or white/albinos colors are a bad sign. Her parents left her but her grandmother took her in and raised her becaue she was not superstitious and her aunt loved her too (Ninas biological mom). Idunn loves to fish and swim and she has a talent to sew. She has a few small scars but see them as survival and strength. Everyone in her village have a neckless with a symbol representing anything related with the ocean and it's animal. Idunns neckless symbol is an orca and her cousin Nina has a seaunicorn (and it very rare). Idunn also has a small shark tooth neckless (her biggest kill).

Even though Idunn has had a tough time, she is always kind and friendly, but she has a dark side when she wants to. But she is quite reserved and likes to be by herself.
