Sherry, you could do a second immortal dynasty in Dragon Valley and a third immortal dynasty in Midnight Hollow.
As people may know, I'm currently trying my (insert large ordinal number here) attempt at an immortal dynasty, the Spirin family in Sunset Valley. What people don't know (until now at least) is that I am already trying my (insert large ordinal number + 1 here) attempt at an immortal dynasty in Union Cove. Scarlet Dreamweaver is the spouse of my founder, and Bubblegum Dreamweaver, Giovarni and Pietro are also part of the 'fun'.
Don't go looking for that ID on the forums, as you won't find it. I'm trying to get through to first generation as an immortal before posting it, and I'm strongly considering just posting the progress without a story for them.
Trusting that I'll break a plumbob and not a saved game this time.
