[Fortuna]: Luck depends on no one....right? (4/3)

The two ships could always split up and reconvene later at a pre-agreed location. Having two ships would likely be a good idea simply because we might have crew members we wish to recruit that could give us a huge advantage, like Big BOssB did.

I do believe the game is rather strict about splitting up. Remember when we lost Hermes? And even if it is possible, splitting up makes little sense from a tactical viewpoint.(Latta, why can't the Mercury come with the Cupid? Is that planet that dangerous? Are you sending us there to die?)

But remember when we lost Captain Hermes?
Hermes was forced to stay in the same place, but Captain Hermes was heading to the same destination while we went on a Detour to the Underworld.
And even if we lose those characters, they don't die. They live.
Not everyone reaches Fortuna, and as we learn from what Cobalt says at the very start of Game One, most crews end up giving up along the way and they pay pretty good.

We could get numerous guaranteed ships.
Also it seems near common knowledge that The Mercury is indestructible, so it may actually be sensible logic.

"I am a fucking coffee cup and I am going to literally throw myself into the centre of the universe for adventure, who's with me. The Mercury is literally indestructible after all lol"

Forgot to mention, but Latta has other traits that would actually make it pretty easy to get other people to go along with her.
