Wynn Byrne is a pre-made playable Sim from the downloadable neighborhood of Dragon Valley, available from The Sims 3 Store. Wynn has 2 points in handiness and 6 points in the cooking skill. Wynn is described as Sarah Dolan's grandmother in her family biography, but it is not shown in the family tree. This is similar to the Prince family, in Midnight Hollow, where relatives are not connected on the family tree due to a missing generation.
When Wynn is aged down in Create a Sim or with the Fountain of Youth Elixir, she has ginger hair streaked with gold, and noticeably large breasts. She is mostly likely a spoof of the grandmother from the fairy tale, Little Red Riding Hood. Wynn's name is a pun of the term "windburn".
