Durnik(VYM017) was born in the Young Ones on August 15, 1997. Their mother was Morgause and their father was Keros, the dominant couple at the time. He had just one litter-mate, VYM018. He and his brother, both survived to adulthood and started to rove together. In 1999, Durnik went roving along with his litter-mate brother VYM018 and his older half brother Morris. The three Young Ones males soon met up and joined four evicted Vivian females.
They stayed together and formed the Nemesis Mob. Those females were Rosemary, Cascade, Sparkle and Imogen. Morris might have took over dominance being the oldest male, along with Sparkle or Cascade who probably won the fight for dominance, being the oldest females and litter-mates. Short after the group formed, Durnik disappeared on August 17, 1999, while Morris and VYM018 later formed the X-iles after being ousted by wild males joining the Nemesis. His brother VYM018 re-eappeared on September 24, 2000 with wild meerkats, however his group was not followed.
