Ok, so that's the end of the hunt! If any of you has a little more you wanted to add to the ending, feel free to post.
Overall, I had a lot of fun, but there was a lot of things I wanted to do but never had the chance for.
The visit to Ee'ith is obviously a big part: I had a whole second half to this in mind where the aliens would visit Ee'ith, who had devised an elaborate ploy to ensure that she had no guards in her private chambers (she's usually surrounded by her protective children, who would obsessively prevent even friendly aliens from touching her), so that she could get a hug from each of the aliens. She would have been very socially awkward and shy, like a hardcore anime fan meeting their favourite Japanese actress in person. It would've been an opportunity to better involve the people who didn't want to go on the hunt.
During the hunt, I also wanted there to be an encounter with an I'ee mass grave: A large, sealed glass cylinder set deep into the ground (drilled through the concrete), filled to the brim with dead I'ee. It'd be like an exhibition of sorts, with a bunker hatch on top that lead to a spiral ramp that ran down around the circumference of the glass grave, so you could see each 'generation' of I'ee born in that family starting from the last at the top and ending at the first at the bottom. Somewhere beneath the top layer would be the dead queen; her remaining children having buried themselves on top of her. Obviously, this got overshadowed by the underground with the robot that Corgan and pals explored.
Also a bit of trivia: I hadn't decided on what exactly the monster would be right up until it was first encountered. The only thing I kept from start till finish about it was its multiple voices, its large eyes and its green colour. I initially envisioned it as a sauropod-looking animal with a long neck and tail.
I hope you all had fun! ^w^
