The Monster Multiverse

Not sure what you guys are on about. The setting has many various extremes, but most incubi and monsters lead pretty vanilla lives aside from being able to have more sex.
One need only look at the overall tone of World Guide 2 and 3. Runya Runya and Greilia are veritable cinnamon roll baphomets.

That doesn't change the fact that two races are meant to face a quite unavoidable extinction because a demoness decided to play god without actually knowing what she was doing...
...Nor changes the modus operandi, approach and behaviour of most the entries in this whole setting.

There are exceptions here and there, sure... So what? But in the great scale of things, they're just that: sporadic and anecdotal exceptions to the grim and unavoidable rule (until... or rather IF the artist decides to toss his fanbase a Deus Ex Machina to solve the convoluted mess that is his setting).
