[Neithan]

I was thinking, the chain Angainor was made by Aule and I don't think he would be able to make something that could contain Melkor's power. However, since Tulkas could overcome Melkor with physical strength, it is very easy to imagine that Tulkas could make a physical chain that could bind Melkor physically.

This is probably the most interesting and important point that I was trying to get at here. The difference between the physical strength and the power of the Ainur. As I see it, they are completely independent of one another, and of what form the Ainu chooses to take. Presumably then a Vala, say Tulkas for example, could take the form an ordinary hobbit and still have all of his legendary strength.


Edit: I meant that it would be easy to imagine that Aule could make such a chain, Tulkas obviously has no skill in that area
