So funny you'd mention that, Carabas, but Vex and I have been talking about what sort of background flavor moment our characters might have had and we were thinking about possibly a trek to some cavern with a pool in it that we were told to find and mediate at, lol. Sorry, just a little coincident that I found amusing.
Anyway, like I said, I think having the sheer amount of flora and fauna present helping to mask our lifesigns, similar to Yoda on Dagobah, combined with some sort of metallic ore component of the caves helping to mask us from sensors on top of a strong Dark Side vergence or nexus hiding our force abilities could easily explain how we haven't been detected even if we were only on a somewhat out of the way planet. Put us on a planet that's, like, a 2P2R3S Astrogation check to get to if you don't have accurate information (which we will hopefully be able to have if/when we leave the planet) then that just makes us even harder to find.
