Propinquity Associates
Propinquity Associates is a transdimensional corporation which provides propinquity (nonfiction)-related services, mainly involving sex (nonfiction) and/or death (nonfiction).
Competition
National Razor
National Razor and Propinquity Associates have a long-standing grudge over who has a better grasp on Occam's Razor (nonfiction).
The Uncials
The Uncials sometimes beat Propinquity Associates to the punch, and there is a certain amount of murderous payback donnybrooking, every time.
These outbursts of violence are inevitably followed by the ritual drinking of Extract of Radium, and the inevitable resulting incidents of scrimshaw abuse.
It keeps happening, over and over again, and you think the Uncials would learn. But no.
So it must be all in good fun, like medieval jousting (nonfiction).
