Levelling is fairly quick at the start of the fjords, even without using Wisdom or turning in quests. I entered early and went from level 13 to 16 just clearing down the mountain path to the bottom (getting a 50% experience bonus for being 3 or more levels below my opponents). After finishing off Maxos Temple (where I got to level 17) I returned to finish off what could be reached before heading to Sentinel Island (between the fjords and turning in quests I got to level 22, so the first mindread on the island brought me to level 23).
The levelling rate does slow down (the experience required to reach a level is proportional to the cube of the level), though you can level quickly clearing the flying fortresses, as well (not as quickly as the start of the fjords).
Drakan: The Ancients' Gates is a PS2 game, sequel to the PC game Drakan: Order of the Flame.
