Isengard has no 'u', Lothlorien I don't think can have a hyphen nor does it normally have one, it's Gwaihir and could you accept Fangorn for Treebeard and Smeagol for Gollum? I wouldn't call the King of the Dead the leader of "the mountain people".
Okay. So Isengard has no "U". Please accept just "Witch King" and maybe rephrase it to be more specific as Gothmog was the leader of the orcs of Mordor. There should be no hyphen in Lothlorien. Lurtz was not the first ever Uruk Hai, it's just implied in the movie. Perhaps be a bit more specific with the mountain people too, as it could be construed as the King Under the Mountain at Erebor. Finally, it's "Shelob" not "Shellob" and "Gwaihir" not "Gwalihir".
