The Fate/ series can be overwhelming. There are different storylines to follow, even though certain characters may appear in multiple installments and timelines. Fate/Extella has attempted to be one of the more accessible spin-offs, at least in gameplay, if not story, and now Fate/Extella Link is here to continue the story that began in Fate/Extra. Fortunately for both newcomers and returning fans, this entry both fixes problems from Fate/Extella: The Umbral Star and tries to help people wade into the depths of its lore.
