I keep getting really weird ones looking at legends mode.
Don't have the saves anymore, but I vividly remember one absurdly goblin-tainted dark world had a bunch of human bandit gangs roaming around. Just about every single one I came across was named something like "The Lovely Kisses" led by fearsome warriors with names like "Ekul Righteoushugs". Pretty much every one I saw was named something along those lines, which was hilarious because they'd be the ones doing the most murdering. I somewhat ironically nicknamed the valley where they all lived Happyville.
More recently (as in, this is for sure the name) there was a Necromancer Tower, the terrifyingly named Playedcaves.
As an aside, it contains roughly 75% of that world's written works, and roughly 90% of those are by one necromancer writing "stunningly" self-indulgent autobiographies and another writing scathing essays on the former, while another wrote a book entitled "Playedcaves: My Only Mistake" so I can only assume it's about the name.
Also in that world, the fittingly-named god of fame and rumors: Gisur LEGENDBRAINS. It is a fitting name, but just imagine having disciples who call you that in prayer each day.
Meanwhile, a vampiress named Icen Pumpkinstrapped went on a "rampage", eating an entire two people and wounding one.
Icen Pumpkinstrapped was also linked to a few battles through direct fighting and people she'd eaten; she fought in the epically-named War of Lances in the less-so Outrageous Battle. During which she killed an elf who had fought in the Disemboweled Clashes, a separate war called the Conflict of Disembowelment, and the Outrageous Attack in the (descriptive) Violent War.
The elf who eventually killed her has a long list of stupid battles; the Battles of Murder, the Outrageous Assault (another one), the Squeezing Onslaught, the Outrageous Onslaught (yet again), and many more. Some of the best include the Violent Siege, the Outrageous Assaults (plural), the Assault of Ransacking, the Assault of Murder, and the (my favorite) War of Sharks.
The best part is, reading the logs for all the battles, they were all epic and massive-scale involving Dwarves, Elves, Goblins, and Humans all making daring land-rushes and killing and dying by the hundreds for their doomed civilizations, and still they come up with names like "the Violent Siege" (where 640 combatants died horribly). Along with one Dwarf named Bootbites, formerly of the Hoary Oar of Portentous Sacks.
