Yes, yes I did.
I was so drawn in by the setting established in both Lobotomy Corp and Library of Ruina that I elected to try my hand at creating a from-the-ground-up D&D 5e Homebrew Module for it, and named it "Star of the City" since it sounded cool and was a reference to the threat ranking system.
I will admit, it's likely not the most creative idea in the world (I did it because I wanted to host a game with friends and this was a setting I was extremely passionate about and could see myself doing long-term), but I was able to set up a solid foundation. I created the Player's Handbook, called "Star of the City: The Fixer's Guide." There are three main classes:

Fixer: Based off of 5e's Fighter, the Fixer is meant to basically act as the tank. However, it has a variety of subclasses that accomplish the job in different ways.
- Zwei, a defensive subclass based mostly on Battlemaster.
- Liu, an offensive subclass that I created myself. Its skills focus on forcing enemies to focus on you and defeating them one at a time while they gain bonuses as the fighting ramps up.
- Shi, a stealth hybrid subclass that essentially acts as a substitute for a Rogue. However, Shi Fixers also have skills that help them tank.

Gunslinger: The "spellcasting" class, but instead of magic they utilize bullets. Bullets utilize a mostly identical structure to spells in 5e, with bullet slots and different levels, or rarities, of bullets. The subclasses focus more on what that specific Gunslinger can do.
- Sniper (based on Full-Stop's Fixers): Uses Intelligence as their shooting modifier, like the 5e Wizard. Their bullets mainly focus on dealing damage, but they also have a few others that provide a variety of buffs or debuffs.
- Shock Trooper (Based on R Corp's Rabbit Team): A melee/ranged hybrid that uses Wisdom as their shooter modifier, like the 5e Sorcerer. This subclass actually turns them into a bit of a tank that has bullets to help give them an upper hand in a melee.
- Commando (Based on the Thumb): A support subclass that uses Charisma as its shooter modifier, with skills similar to the 5e Cleric. The subclass mainly has bullets and skills that provide buffs or healing to allies.

Egoist: Of course, what would a Library of Ruina module be without including Egoists? I put a lot of thought into how the class would work, and eventually decided to take pieces of 5e's Monk, replacing Ki points with E.G.O points that I used in a similar manner. The subclasses for Egoist were a hard thing to figure out, but I eventually decided that they would be based on the circumstances for which the individual's E.G.O manifested. I may rename them at a later date once more information regarding how E.G.O manifests is made clear to us, but so far they are:
- Passion, a damage-oriented subclass. A lot of egoists, such as Xiao and Phillip, seem to manifest their E.G.O due to their immense passion for something. For Xiao, it was a burning love. For Phillip, you could also argue that his E.G.O partially manifested due to his burning passion to actually do something. However, he distorted because his resolve was broken and he fell to despair. Passion Egoists have skills that focus mainly on doing damage, with little else being considered.
- Protection, a defensive/support oriented subclass. Some Egoists, such as Kali/Gebura, formed their E.G.O out of a strong will to protect someone. As such, their skills focus a lot more on being the party's tank and providing defensive buffs to teammates to keep them protected.
- Hope, a support oriented subclass. Some Egoists, like Yan (at least, his cut E.G.O form) formed their E.G.O out of a strong hope. Yan's would likely have been a strong hope that what he was doing would make a difference, and would make things better. However, this was cut from the game. Hope's skills focus on giving party members a variety of different buffs, and enemies a variety of different debuffs and being able to amplify those buffs/debuffs.

I bet you're wondering why I made a post to tell you all of this. Well, I'll be honest: I'm on the fence as to whether or not I should post the actual document here for anyone that wants to start a campaign of their own to use. This is for two reasons:
1. The document isn't entirely done. I focused on developing out the classes/subclasses that my friends actually picked, so some of them aren't done due to time/creativity constraints. I am a college student, and once I'm off summer break I won't have nearly as much freetime as I currently do. On top of that, I'm not sure how balanced some of the skills and bullets are when used in combat. Though, I suppose the latter issue isn't really much of a problem to an experienced DM.
2. I don't really know if there's a demand for this. It could turn out that very few people that play LoR would want to run a D&D campaign based in this setting, and by extension wouldn't care much for it. Which is why...

I'm making this post. I want to gauge interest from people on the forums if they'd like to have a document to use as a baseline for making their own D&D campaign based in the LoR setting. If a significant amount of people would be interested in it, then I'll see about getting the document at least finished (AKA: every subclass is fully fleshed out, and a lot more bullets are added) before sending it. If not, then I don't need to bother and can keep going at the pace I am now. Let me know what your thoughts are.

Until then,
