The Tuba Brothers

Legend says these ancient and immortal brothers perilously wasted away the earliest years of their lives competing with one another over who would champion the progression of orchestral magic. Always overshadowing one another with development and creation time and time again. Some of the greatest musical sorceries ever conceived of can be attributed to these two legendary brass mages. Though, their long and troubled rivalry has clouded their history, to the point that it is difficult to know for sure which brother is responsible for which breakthroughs and developments. To this day, none can differentiate the golden and silver brother's accomplishments from one another. It is said that both became so powerful from their endless struggle that they achieved what few beings ever can, immortality. They now live their lives in secret, making up for lost time to truly appreciate one another as genuine brothers, as they've become weary and tired from their long rivalry, and care little for the world of magic any longer. However, working together, they are among the most terrifying threats known to the world. Should the legends that the Tuba Brothers still walk among us be true, any adventurer unfortunate enough to meet them and anger them, best be wary.

The Tuba Brothers
You can meet them at a forgotten temple within the Brass kingdom. To get to the brothers, you must first resolve a series of music and rhythm based puzzles to unlock a magical mechanism in the temple. After that, a portal will open which takes you to a higher dimension where you will find the two brothers arguing with each other. Once you talk with them, they will give you the honor to have a duel with them (for solving the puzzles from before). The duel is an optional boss fight, after you win they will give you the Tuba of Requiem (one of the best weapons in the game).

Note that is isn’t the only way to encounter the brothers. There are occasionally a rare instance a portal leading to the brothers randomly generated through out the world for a limited amount of time before closing. It is recommended for players to avoid these portals, especially during the early stages of the game. Encountering the brothers through these portals will deem the player as a trespasser and a battle will commence. The only way to win against the brothers at this point is to flee out of the portal because they can’t be damaged by any means. Surviving this encounter will yield no reward (another reason why to avoid these portals like the plague).

Another thing worth talking about is that within the temple you can find a picture of the two brothers together when they were younger. If you give the photo to the brothers they will remember how much they love each other and stop arguing. In doing so, they will help you in the true final battle against Turorochi, the Entropy of Orchestra.
