How to Take Care of a Naderr Frame

People think the same thing whenever they see the Naderr Frame: "How do they manage to keep it so clean?" Curiosity turns to wonderment immediately upon touching the frame. The frame cannot be marred by the smallest bit of dirt, or the tiniest speck of dust. More amazing is that it is completely immune to any pathogen or contagion. A curious Shai apprentice sorcerer wondered, "But does it burn?", and had a go at it with fire magic. The fire dissipated before even coming close. There was also an unfortunate Orc who tried to smash it to pieces, but ended up with a black eye.
