FoW, Underworld or other Money thing in NF

Is there:

FoW
Underworld
or an other good money making thing in Nightfall?

Thanks,

You can access both FoW and UW from the Chantry of Secrets in Nightfall. As far as a new high end area, Anet has said that it is not available yet but will be added soon.

Thanks!
