I'm looking for fantasy recommendations, preferably multi-book series, with big and expansive worlds with many moving pieces, multiple subplots and multiple protagonists and supporting characters each with their own character arcs going on. I want to see something that not only juggles many themes and subplots but is also able to neatly tie it all down and conclude it masterfully in its ending, in a way that:-
a. No character seems forgotten about or diminished.
b. No subplot is abandoned or hastily wrapped up.
c. Every theme that was introduced feels addressed and concluded in the end.
In short, I want to experience an ending that provides full returns on my investment in its characters and its plot and subplots, and doesn't feel half-assed or rushed or poorly executed.
Which fantasy series had the most satisfying and comprehensive endings according to you?
