Trivia

 * “Zenith” is the highest point of a celestial body relative to the observer, in other words when it is directly overhead.
 * "Zenith" can also mean the time at which something is most powerful or successful.
 * It has the most complex crafting tree of any sword in the game, beating the Terra Blade, which is one of its ingredients.
