Drainsoul sounds about right. The other sorta dark one she had was the hellsing UI which I just found the art for. Also found all the shadow UI stuff both Giddeon's original files and your mods I believe. Its all a bit (my memory) blurry. If all goes well they will be attached to the reply here.
Found 2 folders with Shadow UI stuff actually so I'm sending them both. Entirely possible they are both your edits and mine lol.
Let me know if there are others you are after. My folders are a mess so its taking a bit of time to track stuff down.
Holy memory lane batman! I just found all the old T. King interface art in my archives. It's official. I'm a digital hoarder....
