Red Mage Tower

According to Magic Hero, the Fire School is a mainstream school—a group of mages headquartered in the North Kingdom.

Here, "mainstream school" basically means a major magic faction.

Should I call them a large defense contractor?

One of the two heavyweights dominating combat alongside the Ice School.

Hm.

In truth, I don't know much.

I'm a dungeon master who has built my own ecosystem inside a dungeon, after all.

I've never really had much contact with the outside.

And even that was mostly with bastards brandishing swords and demanding mana stones.

Magic Hero : How should I put it... the mainstream schools that have mage towers exist...
