The dwarven council member must be 6th or 7th. The rest can be done in any order. The wizard is quick, as is the orc if you have already cleared the orc camp in the south east of Rivertown. The human quest is slightly longer but straightforward, as is the lizard quest, though with a bit more running around. The elven council member quest involves a potentially difficult fight, so I'd leave that for the 5th (or 7th). I did the imp quest last, to take best advantage of a certain object there. spoiler: [color:"#3A495A"]Specifically, a jug which raises you up a level; if you wait until you are just about to go up a level, level up in that area, then open the jug, you will get another full level. The higher level you are, the more of an experience boost this gives you, though at higher levels you might not need this boost as much.[/color] (highlight the text to read)
