The general technological level of society, at least in the region the PC's inhabit, is fairly medieval with some Renaissance flair.
What that means is that you can find sophisticated crafted heavy armors, glassworks, art, siege engines, large castles, etc. Sort of along the lines of Game of Thrones or Lord of the Rings. All this mixed with a heavy amount of magic to augment all of the above.
What you will not see is steampunk/semi-modern/or psudo-tech, like zeppelins, gunpowder, grenades, ray-guns, cannon, etc. The exceptions will usually entail the workings of gnomes and some others, but usually not to the point of actually effecting the game, and probably not having reliable results.
