To be honest, the Tower of Babel was something I hadn't ever figured out for this setting. ^^; Thinking one what I do have worked out in terms of history in this setting it's probably much stranger then the Biblical version. Maybe some kind of tower construct that recorded languages and produced a language that all people could speak or... something before it was destroyed.

In any case, I'm honestly not sure what being able to use those words would do. Speech is very important to magic, as even if you can mentalcast you still need to say the spell's name in order to use it at full power.

I'm sorry, it's an area I just haven't put enough thought into yet to say if it would work out well or not. ^^;
