I was saddened when it wasn't true when I finally arrived a week after MoP went live. Yu'lon seems to be the only sentient serpent, yet never said she's the reason the serpents are here, or any of her backstory.
I have heard that it took 100 years to build the Jade Serpent Statue. Does this mean that Yu'lon repeats this cycle every 100 years? Do Cloud Serpents have the same lifeline as humans?
Where did they come from? Where did Yu'lon come from? I've read the ingame book of the founding of the order. But there's nothing I see that ties in with it. No other stories. No lore.
I have these burning questions that yearn to be answered.
