A long time ago in a land far far away there was a typical tavern in a typical town with a typical adventurer drowning his aches and sorrows in a typical ale. The world was not so typical though, with things falling from the sky and a big comet filling up most of the sky. "Moo!", the adventurer heard from outside the tavern. Just as he went to sip more ale, he heard it again only more insistent sounding. Curious and definitely under the influence, he stepped outside to see what a cow would be doing in town. The cow looked up at him quite intelligently and stared into his eyes. "MOOOO! You must listen to me - this entire world is going to be destroyed. Gather your friends and meet me here in 2 days if you wish to live." No way was anyone going to believe this he thought, but he gave it a whirl, asking his closest friends to meet him at the tavern at the appointed time. His friends were quite fond of the old adventurer and decided to humor his request and amazingly all were present when the cow appeared. "Moo! You will follow me and I will keep you safe until this world is reborn again and safe for you to rebuild." Given the shaking of the earth and the elementals spawning and erupting volcanoes, it wasn't so hard to agree to follow the cow through a rift in the air. When they emerged again, hard to say how long, they were back but the world had been transformed - fresh fields, green trees, but nobody else survived. To this day, the group of friends uses "MOO!" as a greeting and a sign of trust in each other, for without that trust they wouldn't have lived through the cataclysm.
