[@Inkdrop]Ironically they seem to be somewhat ahead of Zwölfberge.
Late medieval by some unique tech vs the age of discoveries.

Quoting my previous post here:

Oh right, I haven't posted you an example yet. Well, let's remedy it, shall we?

[b]Summary:[/b]
Zwölfberge is a late medieval fantasy nation composed of 12 dwarven city states. They are well-equipped and knowledgable in siege but save for a few like their mercenaries they lack in skill and experience. Zwölfberge can both be invader or defender and it's up for discussion.

Though some of their equipment would be surprisingly effective, depending on a bunch of factors. For example their ships use wheels and pedals spinning an Archimedes screw to propel ships made of steel. Against carronade fire and some earlier naval cannons this could prove to be somewhat effective.

Alternatively you can attempt to challenge my alternate history 17th century Hungary-Poland here:
