Fate/Extella Link constantly provides context
The Fate/ series is one with complicated backstories, but one thing that is relatively easy to understand is the concept of Servants. In each installment's war, there are these fighters that are summoned by Masters, the people participating in this sort of competition for a Holy Grail that can make their wish come true. These familiars are based upon both real and imaginary historic and legendary warriors. With Fate/Extella Link, we have an installment that is incredibly aware of how little people might know about these people and the series and takes care to enlighten them.
