Natives Who Have No Abilities in the World of Able People

Our side: a mage who controls ice (probably), one who can control air, one who can attack mentally, a nanny, and one who (can only) use his brain, well, it looks okay. Opponent: Call the wind and rain, move stars and change battles, incarnate the speed of light, ignore physical attacks, absolute domain (control everything in the domain), reverse everything... Hiss, it's hard to do.
