I suspect that most, if not all registries will require you to provide
at least 2 name servers, because this is highly recommended in one of
the RFCs (forget which one now). It will be quite unusual to find a TLD
which allows just one name server for a delegation.

If your special domain doesn't need to be under a TLD, then you can
create your own delegation for it in a domain you control, with just one
name server if you like.
