Yes, SinVraal (and all the other Gargoyles) told me that i should reach out for the shrine of Singularity. But sadly it's unreachable, as you must be able to fly to enter the shrine.
Who tells me that i have to build a balloon?
It's totally obvious that i should try to get the magic carpet from Lord British! I have no clue why i should try to get a balloon?! Who gives me the clue to build such an air vessel!? i'm totally stuck.
i am aware that i have to ask around in britain for a balloonist, once i have a clue about that - namely ask Isabella in Minoc or ask Selganor, also located in Minoc. still totally puzzled that i should not use the magic carpet.
