Utterly Mad

Okay, at this point it looks like what people object to is the metals. Either because we've had no real explanation on how exactly they work, or because they just look outright magic. Then we've got the whole 'only one person has access to this stuff' thing which makes it a no for me.
Even with Shroomsteel, even though it's a singular race that can produce it the whole race can still make it. Here we just have a singular person who can make it, thus being kind of unfair.
