Has anyone been able to save everyone in the end? And able to find the hidden Iridium Garden?
You need a lot of leadership in order to save everyone, >60 or maybe 70 to be safe.
To find the garden, you would need to click on the choice that allows you to follow your father (the voices you heard when following the automata set to kill Strephon). That should allow you to find the Iridium Garden. I’m not sure if there’s certain stats you need to have that choice though.
