When The Warlords (Teradoc, Harrsk, Delvardus) were added, the Tsoss Beacon pictures didn't exist. That conference image where they're all suffocating was released in the Essential Readers Companion in October 2012, while we released 2.0, the first version with those heroes in it, in August. The icons in the mod currently were created by Xizer's friend on commission based on descriptions of the characters, which were pretty incomplete so there was a lot of guesswork. 2.1 was released afterwards, but I never got around to changing the icons for 2.1 because we were more concerned with some performance issues and Survival mode at that point. They have been changed for 2.2 however (and what's currently Treutan';s icon is being used as his brother Kosh's). Several of the icons in the mod were actually created this way, including Admiral Ar'alani, Melvar, Trigit, Vermel and Ait Convarion. Our Isard portrait was also hand drawn by Codeuser (aka Dr. Knickers) since he wasn't happy with any existing picture of her.
Also another question of mine is: is there, or will there ever be a depiction on what the Galactic Center looks like in the SW galaxy? If not, what do you think it would appear to look like? Maybe it would just be a huge cluster of stars in a relatively small area with a black dot in the center. I have no clue what antimatter looks like.
It's a supermassive black hole, so I imagine it'd look like whatever our own galactic center is supposed to look like although no, there has never been a depiction of it in Star Wars.
