Odysseus' bow is one of the most incredible weapons in mythology. So why didn't he take it to war? Curiously, Homer never gives the bow a name, but he does give it a remarkable history. Thread 👇 Art by @krissydiggs.bsky.social #odyssey #ttrpg #dnd #avallen #rpg #mythology

Speaking as someone who mainly translates light novels (as opposed to other media that are constrained by space or character limits), I really value the cadence and tempo of a passage, so I try to preserve the same feeling I get when I read as when I write, but sometimes "dictionary-flipping"->
