Just some fun tidbits of homebrew from my most recent campaign!

• Gnomes are given a cow at birth which they keep with them always. The gnome and the cow bathe together, eat together, sleep together, and even go to school together.

• Gnomish wedding traditions dictates that a couple must wash each other's feet with fresh milk from the other's cow, slaughter their cows together, and then cook and eat the meat – symbolizing the death of childhood innocence – before they can be considered married.

• “Pointy-ears!” is an insult for lower-class elves because the “traditional elfish features” are the result of inbreeding that the higher-class avoided.

• Dragonborn worship a feathered-serpent figure. In honor of this deity, Dragonborn wear feathered-headdresses (the alternating colors showing how old they are) and bone jewelry (the engravings showing an individual's noteworthy achievements).

• Descending from a demonic trickster goddess, all cats are born with the ability to speak Common: they simply chose to stay silent and let chaos unfold without their meddling.

• Dragons hoard personal treasures rather than monetary treasures.

• Orcs are a nomadic, seafaring people who live in floating villages.

• Elves are horrible tailors.

• Dragonborn believe that when they die they get reincarnated into a bird.

• Elves live in underground, rodent-like colonies.

• Demon Lords can only possess the bodies of children.
