D&D 5E Tiny flavor tweaks

[Lalato]

From my someday-I'll-get-off-my-ass-and-publish-this setting:
- Half-elves and half-orcs are subraces of human;
- Gnomes are the largest of the brownie family of fey (pixie, grig, brownies, quicklings, spriggans);

And the reason both Orcs and Elves can breed with Humans... Because Humans were created from the blood of Gruumsh and Correllon (or whatever the Orc and Elven deities are in your world) during one of their epic battles. Was it some odd mistake of magic? Did another god have a hand in it?

This means that humans are both magical and mundane... and definitely not boring. Also means that humans can have Orc-like tendencies (barbarian rage) and Elf-like tendencies (wizardry).

I'll take a consultant credit in the back of the book as payment.
