*Simply put: During the production there appeared an technical issue.*  
*Instead of scratching the intended idea (or fixing the issue) authors decided to create piece of lore explaining it*

**The Green Lightsaber (Star Wars)** \- So in lore the green is a color of “wisdom and peace” often wielded by Jedi consolers.  
The reason why they came to existence however is because of the sky on Tatooine.  
You see the sky there is clear blue and due to the fact the “good guy” sabers during that time were blue too the blade would blend with sky too much making it hard to see.  
So scriptwriters decided to give Luke a new blade. A green blade.

**Levitation Act (TES)** \- When Bethesda was working on Oblivion, they switched to completely different engine and due to optimization they had to close the cities down into a walled regions divided from open world with loading screen. This created an issue however. Would a player use levitation to go up, above the walls, they could see the ugly low-res textures meant for background. Or, brace yourself, even attempt to go inside the un-modeled cities. So instead Bethesda removed the levitation (teleportation too for some reason) and explained it by the “Levitation Act”. A law made after Morrowind and before Oblivion prohibiting use and distribution of levitation magic.

**Buttsauce character models (Garten of Banban)** \- Aight…I know that even spelling out the name of this…thing…is punished by instantaneous transportation into stinky dimension. BUT LET ME COOK HERE Y’ALL! Because I genuinely love…like…this workaround.  
So yeah…the character models in this game suck…quarter-baked, barely textures, les polygons than a fucking line…  
THERE IS A REASON FOR THIS THOUGH! Y’ALL!  
The reason why characters look the way they look is because they are made of the Play-D’oh like plasticine! Genious! Marvelous!
