Obelisk

The Obelisk of Pagan is a very powerful magical object. Not only is it capable to give strength and power to other magical beings, but also it is a gateway to other worlds, basically a Black Moongate.

The Obelisk was build by the Pagans of Blackrock at the Guardian's orders, to "create" the four Titans of elements to protect them from the "Destroyer". But in reality it was there to strengthen the Guardian's four lackays. Once that was done, the Guardian ordered them to leave, then went through the Black Gate into Pagan, and destroyed it seconds later to erase all evidence.

The Obelisk was smashed into five fragments: The Obelisk Tip, Tongue of Flames, Tear of Seas, Heart of Earth and Breath of Air.

It was the Avatar, who gathered all the fragments, and pulled the power of the Titans into them, to recreate the Obelisk in the Etheral Void to leave Pagan.
