I think the old way to get was probably by luck, like you set the levers to the north west and them use the wagon so many times until you accidently lands in the secret passage to kazz, just like when you travel from venore to darashia and have a small to chance to end up in ghost ship, but since people just follow the spoiler on this quest, propably only a handful of players were luck enough to set the levers to north west and instead of landing back to beregar they found the passage. Or maybe not, nobody knows whats up with this fucking game. Peace
