“Sam Potter. Pleased to make your acquaintance.” - Backstory Codex - Cast Off (RPA-BC) 

Halfling merchant and reporter/supplier to Azariah Blackwater.

Sam is an agreeable fellow who works under Azariah for reasons of self-preservation;

“Let’s just say that I have been helping Azariah acquire certain ‘supplies.’ Your double is conducting experiments. It’s all foul magic and dark arts, if you ask me, but that’s not my concern. I’m just a businessman.“ - Backstory Codex - Cast Off (RPA-BC)

He wears a stunning ensemble to impress those he conducts business with;

A Halfling enters the Chapel. Dressed in a robe and a fine silk shirt, he has the appearance of a wealthy merchant, not a farmer. - Backstory Codex - Cast Off (RPA-BC)

In the end, Sam proves himself a loyal friend;

He appears to view you, and not Azariah, as his master. - Backstory Codex - Cast Off (RPA-BC)

Sam is first caught inside the Ancient Chapel near Jolev and apologizes profusely to you, mistaking you for his employer:

• Capitalize on the ruse and claim his coin.
• Tell him you are not who he thinks he is, and receive details about your doppelgänger and Sam's relationship to them.

At the Ancient Sepulchre, the entranced Halfling is revealed to be Sam's brother, Tom, carrying a map to the Isle of Winter:

• Attempt to search his pockets, and be met with aggression.
• Attempt to break the trance and fail, but grant him a brief moment of clarity.

When arrived at the Isle of Winter, a curious creature greets you, half-man, half-bird, who turns out to be none other than Sam Potter turned by Azariah;

You are greeted at the entrance by a strange creature: a Halfling with the sharp beak and talons of an eagle. It bows its head and follows you as if you were its master. - Backstory Codex - Cast Off (RPA-BC)

• Call Sam off when he attacks Azariah and have a conversation with your maker.
• Grant Sam his revenge on the dark mage and uncover some disturbing notes.
