Sadly, I dont think i will personally be playing Khemia at all. Looking at the story and plot lines, it would appear as though we are no longer following, well, literally us. Now, I'm not brandishing this game at all, and I recommend you play it! It's just not the story continuation that I was looking for. I'm happy waiting for a direct update to Adastra instead.
If Howly has no plans for a sequel, then based on the timeline, KHEMIA should be the finale of the series, and Amicus’s story will also conclude here. I’m not sure what you’re aiming for, but when writing a free FVN, shouldn’t the first goal be to create it for themself rather than to please others?
