[Ravenloft, UA] Racial Paragon Vistana?

[Werther von G]

I'm looking for good ideas to incorporate in creating a Racial Paragon structure for the Vistana (and, by extension, the half-Vistana) in Ravenloft. I imagine that there'll probably be one +1 spellcaster level, and that the half-V paragon will be able to use Divided Ancestry, but I could use some help with the rest.
