ok so you send 3 one way 3 another way 2 a different way and yourself the last way,
situation 1, you find morroc, hurray
situation 2, only one group of people come back with people claiming to have found it, again hurray
situation 3, multiple groups of people claim to have found it, oh noes, logic time
ok, if there are 3 people claiming to have found it in a group go that way because there are only 2 possible liars so you cant have 3 say yes without atleast one truth teller(and in this case you would need 2 and the person capable of lying to tell the truth too)
if you dont have three saying yes, go with the group of 2 you sent out, they found it
loophole answer #2: seeing as you are an awesome player, you port to morroc, then walk to the crossroads, takes 1 min and you know which way to go
