The dwarves considered the sword and shield to be the pinnacle of craftsmanship. And yet, Atlan was asking them to melt it all down and re-use its materials as if it was just made out of iron or some other lowly material.
As blacksmiths, this was akin to blasphemy!
After all, they might be great blacksmiths on their own, but even they could only cower in front of the beings that made these weapons. If they were going to melt it down and remake it from the start, then they would only make an inferior version of it.
"Atlan, this is far too precious of a weapon for you to simply just melt down!" Custodire shouted.
"That's right, that's right! Why not just use these weapons instead of making a new one?" the dwarves asked.
Although Atlan didn't hate a sword and shield, it simply didn't fit his style of fighting.
He didn't like to carry a shield around because he had no need for it.
