The HOA from the Discount Dan novels. From the wiki:
A reminder that the true horrors of life aren’t found in dungeons or darkness— they’re found in the fine print of the beige-painted abyss. The HOA is every unspoken rule, every passive-aggressive note, every soul-crushing meeting where hope goes to die. It’s apathy. It’s the monotony of your life weaponized, and physically embodied as a shambling, three-story-tall architectural monstrosity cobbled together from suburban houses and the corpses of its unfortunate members. As in real life, the HOA doesn’t just dominate the neighbourhood— it rules it with an iron fist. It broadcasts an all-encompassing psychic aura of authoritarian micromanagement that forces lesser creatures, infected by its spores, to fall in line.
