Cover them?

[If one were looking they could almost see the mental wheels turning as Leonardo sat back in his chair and stroked his beard.]

It would be more stable with six... and the belt could make it possible to move all of the wheels at once... That is an idea! I will have to do a few sketches to work out how the gears would connect, but this will be something I try. Grazie Soushi!

[The belt concept had not occurred to him, but now that he thought back on it the image he was shown did have something on it that could have been a set of wheels covered in a belt. ]

Si, you have heard the story! The Apple of Eden was a very tempting fruit that gave anyone who ate it great knowledge, but also cast them from Eden. The Apple is much like that, it is probably why it gained the name. It can grant vast amounts of knowledge to people but it also has a dark side. Some one could become obsessed with it and it can control weak minds.

[As Soushi correctly guessed.]

Very few people know about it. Since it is so powerful it is better that way. But, here in Asgard... I doubt it could do much damage.
