Lambor's Hold

The insect seems to be an enormously oversized dung beetle. That's far from the kind of animal Arphaxad usually handles but he recalls hearing about them as the regular sized versions of them do occasionally hang around stables. They're not particularly aggressive or combative but they are incredibly strong for their size.
Unlike the centipedes, this beetle has probably not been raised for combat but as a sort of beast of burden.

The mayor leans in towards Taz and says: "I think they might be looking for me." Then, louder and towards the small creatures: "But yes, what is your message"

The apparent leader of the three looks between Taz and the mayor for a moment and then says: "The prince says that you have been occupying our home for long enough. We have captured a mighty beast and befriended a powerful lady of magic and if all of you have not left our forest, never to return, by the dawn after the next, we will destroy you!" Its squeaky voice rises angrily towards the end of this message. "None of you will survive!"

"Your town has had many warnings!", the leader of the blue-skinned creatures says indignantly towards Narissa.

"Yes. Ever since we managed to get out of those horrible caves!", one of the others agrees.

The leader shushes him. Then they all grow quiet at Arphaxad's threat. They exchange some nervous glances before the rider gulps and says: "Our leader is the Prince! And we are doing this because this is our home and we have lived here for much much longer than these brief few years that the humans have been occupying this forest!"

"We're also just messengers," the one who's been shushed before quickly adds. "If you kill us, that won't stop the Prince and the Lady. They will just get even angrier!"

"We were here," the shushed one replies. "But these people fought us brutally and drove us down into the caves!"

"Yes," the rider agrees. "And now we're taking our home back. You have until the dawn after the next then you all must be gone. All of you. The lady says you either all leave together or none of you leave here alive!"

"You defeated us last time but not this time!", the other one adds. "Not with the lady and the beast on our side!"

The mayor looks between Taz and the blue-skinned creatures (which includes both Narissa and the three messengers). "Well, our ancestors did fight off the creatures living here, which included fey beings. But in our stories, they didn't look like that!"

"It was us!", the rider replies eagerly. "It was us before you banished us into the evil tunnels!" He narrows his eyes looking at Narissa. "No paperwork. Nothing like that. This is our land. Always has been. Why would we have written it down?"

"We go now!", the other speaking one of the blue-skinned creatures says. "They know our ultimatum."

"Yes," the leader agrees. "Until the dawn after the next. All of you leave together. Or nobody leaves!"

"No," the rider says firmly. "No negotiations anymore! You give us back what is ours or you all die!"

Unless any of you physically stop the three messengers, they're going to leave and return into the forest at this point.

The mayor looks at Taz. "Nobody is still alive from that time. And all our records from back then are our hero songs about how Lambor and his companions settled this region."

"What defenses?", the mayor asks. "We can have Erheim make spears for us but we are not warriors like our parents and grandparents were. If it was just these things, maybe we could defend ourselves. But with all of their vermin, with this beast and the sorceress they apparently employ, we won't stand much of a chance. You might but we don't."
