The Hardhead Genus

"Hardheads" is the colloquial name for a genus of elf-like humanoids. This name refers to the plate of thickened, tough skin covering their foreheads and the bridges of their noses, a trait which is shared by all species of the genus. They also all have digitigrate legs that usually end in paws, thick pointed ears, and tails of some sort. The genus contains three known extant species: the brighthelms, the crownhelms, and the jewelhelms.

Brighthelms

Brighthelms are generally the smallest species of their genus. They are named for the luminescent bulbs on the ends of their antennae. Their eyes are almost entirely taken up by their iris, their ears are hairless, and they have short tails with another luminescent bulb on the end. Their color palettes tend to reflect the environment they grew up in (young brighthelms start off with dark fur, similar to the pups of certain canines such as wolves and foxes.).

Each and every brighthelm has an animal-themed, life-threatening curse, identified by specific visual traits.

But if a brighthelm lives to be older than 50 (or, in the case of those with the Trilobite's curse, beyond their death date), something special happens...

Immortals

Every once in a while, an outbreak of Brighthelms will be born with a new, unknown curse.

Crownhelms

Crownhelms are (with a few exceptions) the largest species of their genus. They come in four ranks that vary in height, as well as a variety of suits that dictate their color palette, pupil shape, and magical abilities.
All crownhelms have a set of horns growing from their foreheads, ears covered in fur, a lionlike mane and tail, and colorful sclera.

Most crownhelm communities (generally called colonies or clowders, though specific clowders may have their own names for themselves) are much smaller than the communities of other sophonts. As soon as crownhelm populations reach a certain level/density, this triggers hormonal changes in crownhelms that cause them to stop reproducing altogether. Crownhelms often associate with other sophonts (but usually not other hardhead species, due to cultural animosity between them and brighthelms and jewelhelms being very elusive and isolated in general). This usually goes well, but the times it doesn't go well are well known - stories about crownhelm communities descending to tyranny spread far and wide, making the issue seem more widespread than it usually is.

Suits

The most common four suits are the Clubs, Diamonds, Hearts and Spades.

There are suits beyond the most common four, with their own affects on coloration, pupil shape and magic. For example, the Arcane Suits, the Cursed Suits, and... the Business Suit.
