Don't the fumes like... fry your brain? You know Mad Hatter and all that? A little disappointing, they should have done something like float pieces of solid steel in the mercury. Oh yeah, and I guess they should have also enclosed it in a hermetically sealed display case too huh?
It's Spain, bro. They don't even know you're not supposed to make stuff out of mercury. Hey, remember how they were conquered by Muslims for like 500 years? And we NEVER were? Psht. Spain.
You mean Frankish leader Charles Martel. Of the Merovingian Kingdom. France as you conceive of it appears much later, after the decadent House of Bourbon fell, Napoleon rose and fell, and Revolution eventually became Republic. It is the model for your own nation, insolent cur - where respect for blood is retained mostly as a contemptuous fear of genetic variations, maintained through stagnant devotion to warped sociocultural prejudices.
A respected master of war chooses when not to fight.
When leaders must bow to merchants, a nation is debased.
