Morkus from Orkus
AD&D also included Shadowfell(plane of shadow), the astral sea(astral plane), domains, dominions, elemental chaos(para and quasi elemental planes), etc. Those do NOT come from the 4e cosmology. They come from 1e Great Wheel well prior to 4e. All you have is the feywild and and so what. So it added one 4e plane to the mix. That doesn't create a blend of the Great Wheel and the World Axis.
