Beside of Tarkin landing a Star Destroyer on protesting people? That happened in canon too, but it went further beyond this in later episodes. Now I wonder if the other massacre and the reasons for it also happened in Legends. I'm also talking about the Empire massacring the Ghor because of needing Kalkite. Which was apparently neccesary for the Death Star. So let's speculate. Gesendet von meinem Nokia G22 mit Tapatalk
The Wook explains it best: "A group of activists were protesting Imperial taxation on the planet Ghorman in the Sern sector. Captain [Sic?] Wilhuff Tarkin's warship was blocked by peaceful protesters who stood on the ship's landing pad and refused to move. With implied permission from Palpatine, Tarkin landed the ship right on the protesters. An overwhelming majority were killed instantly, while hundreds were severely injured, many of them later dying from the resulting injuries. Only a lucky few escaped the ordeal with their lives intact, but almost all sustained horrific psychological damage."
IIRC (and I'd have to check this against the original sources,) the original intent of the Ghorman massacre was that it occurred with Captain Tarkin landing his ship on protesters, and that it was what led to his promotion to Moff and also the beginnings of the Rebellion, culminating with the formation of the Rebel Alliance in 2 BBY. When Revenge of the Sith came out and it was clear that Tarkin was already in a position of authority, the date needed to be moved back. (I think the Last of the Jedi series was the first to indicate that Tarkin was Grand Moff as early as 17 BBY or so.) Oddly enough, I don't think having two massacres was ever a part of Legends, but something similar probably would have ended up happening to make all the references work out. The whole thing is a Legends holdover; they may have started integrating the EU version as early as the Rogue One tie-ins, but it's not based on anything from the films, so they could have left Tarkin out entirely.
...from The Farlander Papers. Note that it only states that he began his career as a warship captain, and that he only rose later on as a result of Ghorman. his early Naval career is completely congruent with most other lore about him serving the Republic, wearing robes of Senatorial favor (per Rogue Planet), and much later having some degree of culpability for Ghorman. The Darth Vader and the Ghost Prison comic has a big plot point about Tarkin already being the only Grand Moff just a few Months into the Empire, which in turn has a few timeline related implications about Ghorman. The continuity around Tarkin and Ghorman shifted around a bit, as the New Essential Guide to Characters outright has Tarkin being promoted to Moff as a result of Ghorman: ...so for a while, the continuity was that Tarkin wasn't one of the first Moffs and didn't become one until some time after the formation of the Empire, though that concept of the original 20 Moffs only came about much later in the Warfare Guide. While it veers off into the realm of fanfiction, the Lady Tarkin series from the early 2000s serves a bit of a time capsule of that earlier continuity: https://www.fanfiction.net/s/965236/1/Ghorman
Darth Krayt Mon Calamari massacre was worse or the whole Vong invasion of the EU makes what happened in Ghorman look like children playing in comparison
