A quote that was datamined from the game
So ya look like mogu are titanic creations after all and not the brutish animalistic race who changed because of the magic waters of the vale that we were led to believe they were.The mogu tell a legend about Lei Shen, the Thunder King. His followers fell to their knees before him. "We will call you 'The Lightning King,'" they said. It is said that he tore out the very heart of the mogu God. And from that hateful act he gained power over wind and storm.
But Lei Shen did not agree. "Lightning strikes in an instant and is over in a flash," he said. "But thunder. Thunder! Thunder proclaims the coming of the storm." "Thunder quakes the skies long before the lightning strikes, and thunder echoes in the hills long after lightningï¿½s power is spent." "It is thunder that sends animals cowering and fills the hearts of peasants with dread. Let thunder be my herald, so that my power is felt throughout the land." "I will be... The Thunder King." Oh my friend - that awful sound. For a hundred hundred generations the crash of thunder filled the hearts of pandaren with terror.
It is said that after the revolution, the Red Crane of Hope placed the rainbow in the sky, so that pandaren would know not to fear the storms any longer. I do not see any rainbows today. Do you?
Fathers and sons. Mothers and daughters. As parents, we pass our legacy on to our children. What values do we choose to instill in our progeny? What will our children learn from our mistakes? What sort of world will we create and leave behind for our daughters and sons? Parents place their children on a path, but they do not always know where the road will take them.
The mogu were children as well. Children of the Titans. They were once a legion of stone, heartless and obedient. By the Titans' command, they fought the terrible servants of the Old Gods.
They shaped the mountains and carved the rivers of the land. And they created a magical cradle of life in a hidden valley that we now call the Vale of Eternal Blossoms.
But eventually the Titans fell silent. And their creations were cursed with flesh. The mogu grew restless. Many generations later, when Thunder King united them, they seized upon their legacy! I truly believe now that the mogu thought they were doing the work of the Titans. They fought against the mantid and used the powers of the Vale to create new life. Ah, but such terrible works! Parents cannot always be assured of the legacy they will leave behind. How especially true this is, when the parents are Gods. And their children - monsters.
