Shit, while I want to start it up, I haven't found the spark inside of me to craft new material for it. We'll see if I can brew something in the days to come but I can't guarantee my desires of revisiting it will be met
Well the way I set it up, was that when he mind melds he has access to that person's memories. Kinda like storing it on a flashdrive that he can access at anytime. It has a negative effect when used on someone who is hostile/angry and can cause the memories and emotions to start overriding Drut's. This ability has been primarily used as a form of interrogation, which causes Drut's race to have insanely short life spans as they go insane and kill themselves or are killed to protect everyone else.
When used on someone that is not hostile like at the end of the last chapter, it does not have the same insanity side effect and can accessed at will for the most part. Basically it is/was an opportunity to develop Drut's, Dalam's, Chim's and Grodun's childhood together and develop their characters.
I have thinking about Gretranin's motives a lot too and I want it to to be more complex/deep than desire for blood shed and power, but how you develop that is up to you.
I might try to find the time (on weekends) to necro the story and come up with the rest of the plot. I definitely don't want him killing everyone, so we'll need to keep key characters alive to advance the story and characterization. We'll see what happens I'll focus on the coup since the mind meld stuff still confuses the shit out of me (mainly since it was your idea and idk how to build off of it with due justice).
