Making the gunpowder is the easy part, making a suitable vessal to
weaponize it is another thing. Gunpowder was around for AGEs before
anyone could figure out how to turn it into a viable weapon. Sure the
Qunari have cannons but just how effective are they? early stages of
cannons in our history where a novelty, combersome and wheren't all that
better then just using a Treb, Catapult or a Balista and maybe half as
reilable. The main problem was, no one really knew how to make a good
cannon barrel, they iddn't understand the right combinations of metals
to make a steerdy barrel, they just made, them packed them with twice
the amount of gun powder they would be used for set them off and if they
diddn't blow up, it was considered successful and sent out into the
feild.
I'm sure alot of people know about Gunpowder and what it can do, in Thedas, but no one really see any real use for it yet.
I don't know, once countries got a hold of gunpowder it didn't take them long to put it to use. Obviously nothing really effective actually came along for centuries, but in the areas of striking terror into the enemy (Which I suppose mages already do) and for breaking down walls it had effectiveness quite early despite the fact the thoughts of rifling and aerodynamic projectiles were far off. It's huge potential was also seen and there was a lot of attention put into imporving it's uses. Let's also not forget the armies of those days were typically clustered tightly together by the thousands, you didn't need much else then something that could fire without blowing your own men up.
Like I said, I just found the notion that gunpowder already has a place with the Qunari so no reason it needs to spread a bit silly, if of course that's what Saibh was trying to imply.
