Whatever happened to the precusor stone?

It reqires some major explaination<br />
<br />
Firstly, concering metal heads, in my opinon, Kor is not the true metal head leader, after all, the statue in Mars Tombs says that they swarm the universe. the fatc that a race of billions of battle bred metal heads couldn't desotyr a single city is slightly absurd. OSo this is why I think kor is only the leader of the metal head forces on Jaks world. So this means he takes orders from, what I call, The Hora-quan queen, who is probably on the metal head home world.<br />
<br />
Secondly, we now know what comes out of the precusor stone was not a precusor, mostly likely only a hologram. The metal heads would not have been fooled by this, as they know what precusors are after fighting them eons ago. This means the precusor stone still has its ultimate power inside, so the metals took it when every one left, and now they await the Queen...DUN DUN DUN!!!!
