Pern would work well. So would:
Harry Turtledove's Darkness series
CJ Cherryh's Foreigner and Sabis books
Hambly's The Dark novels
Ben Bova's Grand Tour
Gentle's Ash
Lieber's Fafhrd & Grey Mouser stories...though that might have to be on HBO.
Moorcock's Eternal Champion cycle...probably broken up into discrete series.
Terry Brooks Shanarrah series
Terry Pratchett's Diskworld
Glen Cook's Garret PI and Black Company novels
David Drakes Northworld and Hammer's Slammers books
Kristine Rusch's Retrieval Artist novels
...and so, so many more.
