I have a few ideas on that front.

I intend to play as the main antagonist, The Witch. Her goal is to build the most powerful army in the world in order to fight off an even greater threat. To that end, she needs to recruit as many reincarnations as she can and conquer the world.

As for worldbuilding, there's definitely opportunities for growth. We've got one major power so far - the Empire of Hume - but humanity tends to fragment more than it tends to unite, so there's definitely other nations in the world vying for power. Feel free to propose some! I've got a few ideas of my own to build upon; maybe one of them will spark your interest.
[list]
[*]Empire of Hume, an imperialistic, orderly, and slightly villainous nation.
[*]Zodiac Tribes, a loose association of nonhuman groups.
[*]An avian nation would be fun. They could be birds, but not necessarily. Floating islands are, like, the [i]definition[/i] of high-fantasy.
[*]A pirate nation! Cliche, but fun. Maybe they're just islanders or something. In a couple RPs I hosted, they were the Coronal Islands, a confederation of surprisingly advanced islanders, kind of like dark-skinned tribal British in a way.
[*]A desert nation that has to get creative to survive. The Uruks (think Saruman's Uruk-hai) of the Cancer Tribe would probably be the most developed here. They're not necessarily evil, but they may be prone to serving any charismatic leader who promises money and women.
[*]A traditional medieval kingdom with adventuring guilds and stuff, to ease players into the New World. I imagine they might come into conflict with the Empire.
