Everyone knows that wizards uses staffs. It makes them more powerful, or so the story goes. The wide variety of staffs used probably seem to be pure fashion or just meaningless appearance to some, but those steeped in the forces of magic know well that the specific form a staff takes serves a greater function. Despite the jesting of bards, staves are not just the wizards overcompensating for something,
Everyone knows that wizards build towers. It makes them more powerful, or so the story goes. The strange design and location of these towers probably seem like madness to most, but those learned in the arcane arts know well that both of these factors are highly important. The towers are not just places for the anti-social magicians wishing to hide themelves (or the occasional kidnapped princess) away from people.
Few people think about the similarities of the wizard’s staff to their tower. Indeed, it is often the case that they seem to be of the same material, and share common features. It’s not because of the wizard’s need to match his things (that’s a Fashion Wizard, don’t confuse them), but because of the Law of Sympathy. It’s easier to link things together with magic if they are similar. And this linking together is the key to the mystery.
It’s quite simple really. Towers are gather up magical energy from the lands, through their design and placement over power veins in the earth. They then transmit the energy to the staff (or staves) that are linked to it. And then, the wizard(s) can throw that power around, however they want to. This is why stealing a wizard’s staff is a good strategy to defeat him (and also to make him really pissed). Though if you want a more permanent (though not the most permanent) solution to the wizard, you should really take care of the tower itself.
On another note: while it’s true that there are wizards living in their towers, this is of secondary importance, and more of something of a convenience. Why build another house when you’ve already got this pretty tower, filled to the brim with magical radiation? It makes it quick to recalibrate the staff to the tower if the connection is broken, which is sometimes useful after a hard week spent adventuring. Though, as noted, these towers have a tendency to be located in rather strange places…
