A prey group answers to the id the game publishes and to its slug, and a name
is slugged before it is tried, so /prey/arachnids and /prey/Giant Arachnids
are the same group. The id wins where the two collide.

The two handles are the same string on 29 of the 35 rows, the game already
writing this track's keys in kebab. The six where they differ are the ones the
slug is for: amazon-camp is named Amazons & Valkyries, nightmares is
Nightmare Creatures, reapers is Reapers & Smiths.
