Vellys Party People
The Velly story! She's the main character and this is her supporting cast :) and kids obvs. You can ask for slots for these characters but they will never be for sale.
The Wandering Souls
People who are loners or don't quite fit into a group. These guys could be asked for about sales/trades but I am unlikely to say yes. Feel free to inquire about slots for fawning!
