Although I understand some of the mechanics behind the removal of certain spells from Oblivion that had appeared in Morrowind there are others I believe would have been a fine addition to the game, for example Mark & Recall. Levitation and Feather Fall (all the similar, which ever it was called).

Will we be seeing a return of one or all of these spells in Skyrim and how are the spells intended to work, are they perks unto themselves or individual facets of the skill they fall under?

Doesn't sound that much more broad. I know there is much debate over whether levitation is a practical game mechanic or not. Slowfall is something I would like to see return though. Teleportation is unfortunately useless with fast travel (time is irrelevant in TES games).

I think slow fall was either pulled because of several level designs like the white gold tower in a certain guild quest, that or that its was just plain forgotten.

I suspect that there will not be any (or many) new spells introduced since they have put that effort into new ways to manipulate the old spells, such as a flame thrower type attack (or cone for frost or lightning) as well as spell traps and all that. I think that levitation would be perfect for the mountainous regions of SK, asothers have said, but I doubt it especially since todd was claiming that the mountains would make the map seem bigger since you have to walk around them, given that I doubt levitation will return.

Morrowind didnt have a "broad spectrum" of spells. Most were the exact same effect but having varying duration and type (touch or ranged).
