Investigate the disappearances in Bergana.
After Vestige wears the Forebear Disguise:
"Welcome to the fellowship hall. You're not from Bergama, though. Are you from Sentinel? No matter, as long as you're a Forebear."
- I am a Forebear. "Then you may come and go as you see fit. Would you like me to get the door?"
- I'll get it myself.
- "I'm sorry. Only Forebears are allowed in today. We do welcome guests on some occasions, so I hope you will return at another time."
