Sometimes I think about the way the Fellowship came together. How is it that 4 hobbits ended up on a perilous journey to destroy the One Ring to rule them all, while they had so much countryside to cover still? Elrond, Galadriel, or any of the elven warriors could have accompanied the Fellowship and aided in their quest, but somehow this ragtag group of 9 random dudes decided to ban together, following the advice of a 50-year-old hobbit who's never left the Shire.
However, that's the point of LOTR, isn't it?
They never had any chance of making it to Mordor in the first place, the miraculousness of the story lies deep in the characters and their serendipitous success as they made their way through Middle Earth. We can speculate all we want about the ideal lineup for the Fellowship of the Ring, but ultimately, the odds and ends that came together under one banner are the men, elvens, dwarves, hobbits, and wizards who made it happen.
