Dungeons and Dragons Alignment System as Described By Fish-(or, "What Happens When You Give a Tumblr Blog to a Bunch of Self-Proclaimed Geeks With a Propensity for New Memes")
It was decreed that Tilapia should represent neutrality (because it is usually tasteless), Snapper evil (because it is red and angry looking), Tuna good (because good tuna is really freaking delicious), Sardine chaos (because sardines can either make or break a dish arbitrarily) and Salmon law (because salmon stay together).
Taking these in combination, we have
Sardine Snapper-Chaotic Evil
Salmon Snapper-Lawful Evil
Tilapia Snapper-Neutral Evil
Tilapia Tilapia (or "Tilapia Squared")-True Neutral
Tilapia Tuna-Neutral Good
Sardine Tuna-Chaotic Good
So what happens when you put a Salmon Tuna Paladin in with a Sardine Snapper mage and a Tilapia Tuna ranger in a party? Seems like a fishy combination...
