Are there any risks of softlocks/extreme backtracking in Wizardry 7?

Just started playing Wizardry 7 with the same party I did wizardry 6 with. I’ve currently done the Ogre castle and the Rat ruins so far, but I’m still struggling to understand what I’m actually trying to achieve here, is my goal to get all the maps or is it to get a bunch of random macguffins across the world, and if so is there a risk that I’ll soft lock the game or have to spend 10+ hours backtracking past boring combats?

I’ve spent so much time fannying about that most of the maps seem to have been collected either by me or NPCs so if I just need to find them and go to a place I’ll take my time. But if I have to go over every square with a fine toothed comb unspoiled and risk having to do combats that are braindead easy for 10 hours straight because I have to walk across the entire world to get to the starting area that would put me off majorly.
