One possibility would be "Fairy Tale Adventure", although
afaik it had no sequels.

King's Quest (plus other *-quest series) were published
by Sierra Entertainment. Try to go there and onward
in your research.

Good Luck !!
Faery Tale Adventure, which I had on the Amiga, did indeed have a sequel. But
you didn't really play a sorceror in that game, although you could obtain a
wand later on in the game.
That's it thanks :)
