I'm making a world, help!

Im making a world, and i just really need things to put in it, cause i want most everything to be unique in it. And I've been getting ideas from my new bf, who makes worlds, but i still want help. Currently the magic system is based around these things called spherules that totally are not inspired by the automaton from slay the spire. and the spherules will not be like fire frost lightning, you know, the classic magical thing. they will be entirely unique magic elements. Oh yeah I'm back btw.
