After the End Times

 Not long after his expidition to the Void with Ibani, Gaster is in the bar, working on his laptop, which shows a mess of code - the early stages of a computer program being written. Another tab on the screen is a map of some kind, with several spots marked on it. 


He's got the beginnings of a plan of attack, so to speak - it's just a matter of getting the right tools for the job.
