@Vankseal Serozan: No need to apologize; we all make some mistakes here and there.
Anyways, since magic is overused, yliakum has the proper biomes, etc. Then I'd say it could exist. Heck, it could have a history for fireworks, or it could be a new thing. But Yliakum's evolution of weapons point to something, (pardon the pun,) explosive. The dwarves are known for strong metal alloys, and there are a fare share of engineers in the population of Yliakum.
Considering the way things have been working for about what, 750 years, in addition to technology and knowledge from other races, then Yliakum could very well have gunpowder.
(Magic and melee are overused. I'd say it's time those who use ranged attacks got a bit of use.)
