Queen Tuba

The Tuba Queen's blood lust is rivaled only by her desire for complete domination. While not possessing the sheer strength of her regal husband, Tuba Queen displays an otherworldly level of manipulation over sentient beings. As such her subordinates are never far from her, though the Tuba Queen is of the opinion that "brooms are to be used, not seen." It is said that her iron will can even impose upon stone to move of its, or rather her, own accord. As a royalty of the Brass Kingdom, Tuba Queen strictly refuses to overexert herself choosing instead to delegate immense tasks to others, perhaps even allies of her opponent. Although, one can only guess what would happen should an assailant force Tuba Queen's own hand to respond...

Quests
You meet her indirectly midway through the game after causing the Brass rebellion through her many messengers. She informs you that her husband became mad with power after being corrupted and desires an end to the bloodshed he caused. She would give you quests through her messengers and competing them would get you money, gear, weapons and experience.

These quests are mostly in a form of a bounty, an assassination, a sabotage or a kidnapping. These hits are usually high leveled Brass Kingdom bosses you've already fought before but in a different skin (for example tuba knight, by this part of the game, you should've already defeated him, so this tuba knight you'll be fighting is not the same one you've fought before). There's also a good chance that these boss clones you've fought before will have an additional ability or a power up or some additional minions or sometimes even multiple different bosses you'll have to fight at the same time. Defeating these bosses will have a good chance they'll spawn with them their weapons, armor or on a rare drop, their spells and abilities. Note that these bosses will only have a 20% chance of dropping any of their gear. You will also have a rare instance to be sent a quest to fight optional bosses you haven't encountered before in the game. These bosses are optional and are only recommended if you're really confident in your abilities or if you are high enough leveled.

The assassination, sabotage or kidnapping quests are all stealth based. You sneak in an area dictated by the quest, you go and either fight and kill this one enemy, destroy this thing or take this person and leave while sneaking back out or fight your way out. Note that quests like assassination or kidnapping, your target will have a chance of either running away or stay and fight you. If your target leaves, you would have failed. The sabotage quest usually don't have your target leave, but sometime the thing you were suppose to destroy can sometime elope with your enemies.

For players that just want good loot or high enough enemies to grind for XP, Queen Tuba's quests is usually a good pick. But for players that are here for the story and role playing, eventually, every now and again, what she's requesting you as the player to do will start becoming increasingly questionable.

(Spoilers, for anyone who hasn't gotten there yet)

For example, the messenger tells you to go and sabotage a supply caravan that's transporting weapons to a Brass Imperial outpost. However, the marker on your map sends you to somewhere that's not even close to any Brass Imperial outpost. This caravan is heavily guarded by a Tuba Defender, two Tuba Gunners, four Tuba Infantry and a Tuba Priest. So you defeat them and loot the caravan. But what's inside isn't weapons, but medicine. If you were just here for the loot, the enemies drop some pretty good gear. However, for adapt lore enthusiasts or anyone that's paying attention to the map, the caravan path doesn't seem to be heading to any outpost, but a refugee camp. After going back to the messenger, he will congratulate you on a job well done on behalf of the queen and will tell you if she has any thing else for you to do. Quests such like this makes you question your actions and her motives even more.

Epilogue
You finally meet her in person after you defeat King Tuba II. She will congratulate you on a job well done and rewards you by knighting you and as well as your companions as the royal champions of the the Brass Kingdom. You will then have two options: either to become a new king, or to leave.

If the player decides to leave, then Queen Tuba will have absolute control over the Brass Kingdom.

If the player decides to become a new king, then the ending will depend on what was the Player doing, and was he learning the dark magic, or light. If the Player decided to do good and right things, while learning light, then he will become a good king, the Kingdom will prosper and the folks will be pleased. If the Player was doing bad and unrighteous things, while learning the secrets of the darkness and the dark magic, then he will become a more successful version of his pre-successor. His ruling period will be considered as a pure tyranny, yet none will dare to stand against the new king, as he will be to cruel and strong.

Queen Tuba the Mad
If the player chooses to either leave or to become a good king, you will then enter a fight against the true final boss of the game.

You will fight Queen Tuba the Mad.

If you leave, there will be some credits rolling and a "good end" ending at the end. Right up until the screen goes red then an explosion happen and everything is on fire, followed by a wicked laughter, presumably the Queen's laughter. The landscape you've once traversed will be in flames as smoldering rocks rain down from the sky as well as ash. Speaking of the sky, the sun is there, but the sky itself is black as if it were night. You will have to traverse back to the Brass Kingdom and back to the castle while being surrounded by a hellish landscape that was once the familiar game's over world. You get back to the castle, but it's littered with the dead and dying. Once you enter, you'll be faced to face with the embodiment of evil that is Queen Tuba the Mad in a monstrous form obtained by absorbing the powers from an ancient Brass God, known only as the Tubasolator.

If you decide to become the next king and on the path of good, you will still have the same credits rolling, as well as the "good end" ending at the end until the screen goes red, explode, everything burns and evil laugh, you get it. This time however, you will be in your royal chambers, you will look outside, the landscape is burning, smoldering rocks falling down and ashes too. You will make it down the castle but is greeted by the dead and dying on your path. Once you finally make it to the throne room, you'll be faced to face with the embodiment of evil that is Queen Tuba the Mad in a monstrous form obtained by absorbing the powers from an ancient Brass God, known only as the Tubasolator.

If you decide to become the next king and on the path of evil, you will still have the same credits rolling, as well as the "good end" ending at the end until a question mark is placed by the end of the "good end". The screen will then display your player character's portrait with the name plate on the bottom titled as "King Tuba III", implying you are now the next big bad.
