First thing first: There was no way I could have possibly known you have a terminal illness involving a brain tumor. If you've publicly spoken about this before, I certainly wasn't privy to it. It is unfortunate and I'm sorry you've had to deal with that, @Grisham4life.
With the certain knowledge of your mortality in front of you, I'm not the one to decide what your legacy is. That's on you. However, I might suggest filling in your "About Me" section on the Nexus so folks might see how you want others to see your legacy. Plan ahead, and let those that read the page know you before you are gone. I should hope your legacy is more than an old large scale KotOR mod (and assorted ancillary mods) - especially as you haven't created any of them. You are not defined by your illness. You might want to talk about that book, for example.
As for my mod, if you had asked me for permission beforehand, I not only would have given you permission but also thanked you in the process. However with all that's now gone now, that window has closed. And if it isn't too snobby of me to mention: for someone that liked my mod enough to appropriate it, I haven't seen a review of the mod on the page.
I accept your apology and consider this matter closed.
Best of health moving forward.
