Its already been said what she wants. She wants to get rid of the humans currently inhabititing remnant, and replace them with ones capable of magic and less likely to fight amidst each other that she'll rule over. To that end, she wants to gather the relics so the Gods will be brought back, nuke Remnant, and leave her alive like when it happened the first time, seeing as they can't seem to kill her.

Basically, rather than do Ozma's mission and hope humanity can become a utopia, she wants to clear the board, then start over with a new set of humanity more ideal in her eyes to make such a utopia.
