Here is the last release of this year's CCSF, by myself (Allekha). One of my favorite C2 breeds is the Uriel Norns, with their beautiful dawn-colored wings. In DS, I still often favor Gargoyles and Butterfly Norns. You might notice a pattern.
These are winged norns for C1. Thanks to a quirk of partially-implemented code that nobody else seems to have exploited yet, as far as I can tell, they are not overwriting - you can still have your regular C1 Banana, White-Haired Pixie, and Horse Norns next to the winged ones. (Technical details will be forthcoming at some point for those who are interested - the short version is that the wings use the tail slot, which was not used until C2 but seems to have been fairly well implemented in C1 already.)
"Norns with wings that flap about and fold in sometimes, based on Tarlia and Kezune's fixed genome. Fit in slot 0, 1, and 2, without overwriting original breeds. I don't recommend crossing them with norns that have body slots 3 and above, as it will look strange due to the body data not being there (yet). They should crossbreed okay with non-winged norns; however, they may not inherit all of the pose gene edits and so might not move their wings as much. Perhaps that's realistic, the crossbreed not quite inheriting everything they need." Integrates Jessica of Discover Albia's baby male norn body data fixes, with her permission.
