As others have indicated the Dawn figure is available at Hivewire3d.

Dawn is not a figure from the Victoria 4 or Genesis 1/2 families. Dawn is a completely new figure.

Dawn is weight mapped similar to Genesis 1/2, but Dawn uses DAZ Studio native weight mapping in DAZ Studio and Poser native weight mapping in poser. The result is that clothing for Dawn is not compatible between DAZ Studio and Poser. The differences go deeper than just material settings. 

Many Dawn products are available in both DAZ Studio and Poser versions, but some are only available for Poser.

Victoria 4 and Genesis 1/2 clothing will not directly work on Dawn. Some people have created a V4 clone for Dawn in DAZ Studio that allows you to autofit Victoria 4 clothes to Dawn. Unforntuately, because of copyrights, this clone cannot be sold commericially.There is a tutorial someplace on how to create the V4 clone.
