Ok what is it, it's on one of the Pics of the FINN figures. Does this mean that Galen Marek (starkiller) Vader's secret apprentice from the force awakens is somehow connected? Maybe it's Kylo Ren's real name or possibly just the name of the first Order's super weapon
Starkiller Base is just the name of the military base that General Hux commands (as seen in the parade ground pics) and I believe we'll see that the Starkiller is the name of the new super weapon.
Might not be canon but using Starkiller officially in the movie must be a nod to the initial draft of the first star wars later used for the force awakens character. My money is on the Starkiller being a new Deathstar only instead of blowing up planets it destroys stars however that was also used in the expanded universe just can't remember the name of the books.
No, that's exactly what people having been saying it is. Starkiller is canon and refers to the new base/ probably super weapon. LK and JJ said it was specifically a nod to the old drafts. Galen Marek is gone.
