"Lighting the Jupiter Lighthouse the same as lighting the Mars Lighthouse"?

[Douglas]

On top of the Venus Lighthouse, Saturos and Mendardi stated that "lighting the Jupiter Lighthouse is virtually the same as lighting Mars Lighthouse".  What did they mean by this?  I've always assumed it was because the Mars Lighthouse is so close to Prox (where they're from), and so they could basically return home after lighting Jupiter...

I didn't get that far (sorry people) but wouldn't that mean that the way to light each lighthouse is the same?

Atop the Venus Lighthouse (the 2nd out of four to be lit), Saturos & Menardi stated that they basically only had one more lighthouse to ignite.  I don't understand what they meant.

They probably already know how to get through The Mars Lighthouse since they were raised near it.
It should be fairly easy for the warriors trained/entrusted with the quest to get to top.
I'd imagine it might be how they were trained.

So, in a sense it's not one more beacon to light, but one more tower of confusing puzzles to wander around until they figure it out or the heroes do for them.

Your conjecture does make sense, Ailan. My thinking was pretty much the same.
