Well, I had a fairly fun adventure in my Illithid dominated world.
I started off as a steel dwarf in a mountainhome that's isolated from the rest of the world by a square of mountains you have to manually walk over. No problem, I started walking at night so I wouldn't get too distracted by shiny things and travelled for a while, when I thought I'd gotten far enough... oops, can't travel because something can see you! So I started walking back the way I came to clear my way out and killed some eagles, some more eagles, another group of eagles, a few more eagles, and OH MY GOD OGRES. This was actually my first time seeing ogres in Genesis so I wasn't sure whether they were lethal or deadly.
I'd made a crossbow and bolts from some of the eagles I killed, so I shot an ogre and it took damage. "If it bleeds, I can kill it" is the motto I play by in adventure mode, so I dropped the crossbow and took out my trusty Wrought Iron Battleaxe, and proceeded to carefully kill the ogres one by one. Ogres dealt with, I was able to travel to the single surviving dwarven mountainhome on the other side of the mountain, to look for
spearcatchers valiant allies to aid me in my quest! Unfortunately there were only about 10 dwarves living there and I could only find one sword-dwarf to come with me. Oh well, onward to check out the illithid cities!
The illithid cities weren't hard to find, they control about half the map. Unfortunately when I arrived at the nearest one I quickly found out that you can't talk to them, only the non-illithid slaves. I felt greatly disappointed for all of 10 seconds until I realised that this just means that there's absolutely no reason at all not to begin the Age of Death with them.
Next on my list of fun new friends to make was werewolves! So I travelled halfway across the world without too much fuss (well, my sword-dwarf friend picked up a lot of bad-ass scars, but I was fine) and arrived at one of the werewolf forest retreats, only to find that they, like the illithid, are mute and therefore I cannot have a werewolf wrestler companion, alas
My next plan was to find a civilization near an Illithid or Werewolf civ who would be at war with them and see if I could pick up a mission to kill an Illithid or Werewolf, just as an excuse to start a rampage. The unlikely heroes in this case were the Sylvan Elves, who are either about 2 years from being extinct or just outside the range of the largest Illithid empire. There are 3 quest givers in their capital forest retreat, the queen, princess, and druid, and they all sent me after an Illithid high priest at a nearby dark fortress.
I arrived at the dark fortress with my trusty and scarred sidekick the sword-dwarf, and 2 serpentfolk warriors I'd picked up on the way to the elven kingdom. As fate would have it (I honestly didn't want or plan for this to happen. This is just a result of picking up the first warriors I find that are willing) they are an obsidian dwarf and 2 serpentfolk salamanders. Those of you who have adventured with similar companions know what this means in terms of combat, and those of you who haven't, should
Anyway. I arrived right at the edge of the temple, with the illithid high priest about 5 paces from me, and the dwarf neaby, but the serpentfolk were out of sight. I charged at the high priest while the dwarf decided to take on some serpentfolk slaves that were nearby. My fight with the high priest was a draw, neither of us could inflict any serious damage. He had no weapons and I could only dent his forcefield. He then decided to fly up and over to the other side of the temple structure where I couldn't easily follow, and my serpentfolk allies, some more illithids, and more slaves showed up.
The fight was on, fire and medusa breath flew everywhere. The dwarf became paralysed and a bunch of slaves strangled him to death. I dropped my axe and picked up his crucible steel short sword, thinking that might be more effective against the illithid. Conveniently, the high priest came back within reach and I was able to test it. One swing and one decapitation later, my mission was complete, and I was ready to return to the elven capital for my next mission, if not for my serpentfolk allies, who were in a bit of trouble. One had become paralysed by something I think medusa breath from a slave, the other was struggling to fend off four opponents. With the crucible steel short sword in hand, I easily defeated the 3 slaves and one illithid who were fighting with my conscious ally.
I could have left after that, but I didn't want to leave my paralysed salamander companion behind. I saw another illithid priest on the far side of the temple, so I headed around the edge of the pit to attack him, to defend my paralysed companion. Unfortunately, when I got to him, he swung at me and I dodged into the pit, momentarily stunning myself. That was all the time the illithid needed to fly down and strangle me to death. Opportunistic bastard. Can't blame him though, it's what I'd have done in that situation, if I had wings.
Oh, I'd like to note, that in this world, while the illithids do control about half of the world, every other race is still alive, except goblins and nords. Goblins have always died out because they are too aggressive and weak. Nords in this world, 2 of their civs got killed within 50 years because they were too close to illithids, the other 2 civs got killed in year 190 and 450 by serpentfolk civs, after 10 year wars. I don't know if that means nords are too weak/lizardfolk too strong, because I don't actually know how these war results are figured out. (except that it takes illithids about 5 years to wipe out any civ they decide to declare war on, it seems)
