Oath of the Hero | Paladin Sacred Oath, and on inspiration

The story of this homebrew is a little interesting. For a long time, I've had this idea for a campaign in my head I call "Temples & Triforces": in other words, Legend of Zelda-themed Dungeons & Dragons. I enjoy homebrew, and I enjoy the game design work of a Dungeon Master, so I figured that given enough time and inspiration, I would be able to create content that would make my idea possible.
