I mean Kada... the player Kada El stopped playing ages ago, dunno why though. 
I believe that the key to solving this mistery is the fact Kada was the mistress of nearly all oldbies back then.
My guess is that somewhere during or after the Cabal war, Seperot decided that he wanted an army of oldbies under his control (which would be only natural considering his "army of dragons" thing). Now to achieve this, he first needed to somehow get Kada under his bidding. He created a secret committee, the sole purpose of which was to find out as much about Kada as possible.
And so it happened.
One beautiful day he approached Kada and said: "From this day on your doing my biding. You're oldbies are going to do eveyrthing I tell you their gonig to do."
Obviously, Kada was shocked. And not even by Seperot's bizarre spelling, to which everyone were used to anyway.
But after Seperot's subsequent words, Kada was confused no more...
"...or I'll tell everynoe your realy a big hairy guy."
Kada was shattered. What should he do? Have his unblemished reputation ruined? Or give this unstable maniac the power for which he yearned so much? After much deliberation, he decided only one right thing could be done in such situation...
He disappeared.
That's my theory anyway, and I think everyone will agree it is a very plausible one.
But to stay on topic:
Everyone gather around. Sangwa will now sing the new Dark Empire anthem.
