That may be, but it's not a type of magic that I've generally been too fond of in any place where I've seen it, and if it really is the only kind of magic available, then I'd rather just not use it. It kinda excludes the entire spiritual side of magic, and means that divine spellcasters aren't using magic because of the grace of their patron god, but because they know how to speak a limerick in the Ancient Language. Would Gnolls (hyena folk) fit into the setting at all?
