The ancient Chinese had their own system of organising the stars, which revolved around, amongst other things, grouping 28 phases of the moon into 4 sets of 7 according to the compass points. Each set had a symbol - the Azure Dragon of the East, the Black Tortoise of the North, the White Tiger of the West, and the Vermilion Bird of the South.
I don't know much about this, or about ancient Chinese history or culture, but I do think having the points of the compass associated with symbolic beings really fucking cool.
It gets me thinking about a recent conversation on G+ on how dice can communicate four different things - position, number, number of sides, and colour. Roll a fistful of different dice and you get four different variables, or five even if you include how a d8 can 'point' in a direction. Wouldn't it be interesting to have a set of dice of four different colours, each symbolising, say, one of the elements - or, respectively, the blue dragon of the East, the black tortoise of the North, the white tiger of the West, and the red bird of the South?
The way I envisage this working is, there are literally four gargantuan beings in the world, each at an extreme point of the compass. (The world being a big flat disc - duh.) And they each influence the world in different ways. Let's say, for the sake of argument, the blue dragon of the east represents warfare and conflict, the black tortoise of the north represents protection and survival, the white tiger of the west represents trickery and cunning, and the red bird of the south represents beauty and passion.
Any time any player needs to roll a dice, they can pick a colour and explain why it is relevant. Most obviously, if you were rolling to-hit in combat, you'd probably want a blue dice - but you might want a white one if you were backstabbing or ambushing. If you were trying to charm a princess you'd use red - unless you were impressing her with a display of toughness, when you might use black.
Then, if you succeed on the roll, you get a bonus of some kind from the influence of the mighty being. Because as any fool knows, the mighty beings govern everything within the purview that happens here on earth. And they will directly intervene if invoked. But their interventions are capricious; if you fail on the roll, you fail badly.
So, in combat, you roll a blue dice to-hit...and if you hit you do extra damage because the blue dragon of the East guides your blow. But if you miss, you slip or drop your sword because the blue dragon of the East spurns you. If you manage to charm the princess using the red dice you are extremely charming, because the red bird gives you its blessing...but if you fail she not only isn't impressed; she wants you destroyed, because the red bird takes against your hubris. Etc.
If the player in question doesn't want to invoke one of the compass point mighty beings, he just picks a neutral dice. Green or yellow or whatever. And the result stands as it stands.
A half-formed and exhausted thought for a Thursday. What were you expecting - something useful?
