They appear to be acting of their on free will. They're just very friendly and subservient. From the 2 encounters you've had with them so far, they seem to go out of their way to avoid violence.

Tempe smiles a crocodile smile only cause he has no choice in the matter. Remembering the man putting away his sword instead of attacking when Tempe was trying to capture him. He looks for any of the ones that were at the hole not long ago. 23 perception. Passive 14

@Tempe

You spot the one you captured briefly before he escaped. He is offering Zenodor a refreshment.

Tempe walks over and offers a hand shake.

Not familiar with your customs he mistakes your gesture for a desire for refreshment and proffers you a beverage.

(Lol) Tempe holding the drink looks at the man and bows keeping his eyes on him "Perhaps we should tell them about our recent acquisition" He says to Petcan "Unless you think it's unwise."

Petcan shrugs. “They say they don’t wander the island much. They probably didn’t leave those things there. I suspect a third party.” 

Petcan asks islanders: “Are there other people around besides your village?” 

They explain that sometimes there used to be visitors something like you but not for a long time.

Tempe tilts his head in question. "I meant the Head."

 Zenodor takes the refreshment and thanks the native. However, he does not drink from it and at the first opportunity will put it down while fiddling with his equipment, inconspicuously empty it, and then walk around with an empty bowl/cup/goblet/whatever instead.

Randall:

Continuing to watch the natives and observe their interactions while learning as many phrases in their language as he can,, Randall says, “Yes, I think we should tell them we eliminated a dangerous threat we encountered on the way here and show them the head—but it needs to be explained carefully first so we don’t scare them.”

Once Petcan explains, Randall will slowly remove the chuul head from the bag of holding.

“Oh, that!” Petcan elaborates about the monsters to the villagers 

(ooc: sorry for the absence)

The villagers are shocked by the head but glad you slew some monsters that were in caves near them.

Randall:

”Let us continue work on the map and the location of the Purplewraiths before the translation spell expires,” suggests Randall.

During al this talking Bow will take some refreshments from the natives and happily eats/drinks them while watching as the others talk. Waiting till they move on. Thinking about what the colonists will think about other people living on the island.

 Petcan translates

"I've not met so many happy people since the monastery" 

The natives are able to mark 3 locations on your map that have concentrations of Purplewraths. They also share their limited understanding that the Purplewraths are simplistic plants and don't react like complex life forms. (They use their simple language to convey these ideas. I paraphrased for convenience.)

Tempe says to Petcan "Ask about the huge bonfire please." since this if what brought them here in the first place.

Randall:

”Yes, of course, Tempe.  The bonfire is how we found them,” responds Randall, looking around for any piles of ash or charcoal that might be the remains of a huge bonfire.
