Curious about My Dad’s Monster ManualCheck out my first post on the subject.

Time to show off another critter created by my father and I created! This time he totally rewrote the story of the ankheg. He saw them as wise, amphibious critters. Take a look!

Lobsteronian (Ankheg)

Oh! This creature is a wise creature.

Lucian J. Introcaso

Standing between five and eight feet tall, lobsteronians live in isolated swamp communities reminiscent of their home planet. They can live more than five hundred years, achieving adulthood around age twenty.

Interstellar Wise Folk. Lobsteronians seek enlightenment by teleporting to different planets in the Material Plane and learning about the world’s inhabitants. If well received, they may stay on a planet for a decade or more.

When lobsteronians come to a new planet, they make themselves comfortable in a remote swamp. Then they send out messengers to seek nearby communities and offer words of peace.

Lobsteronians never reveal the name of their planet to others for fear that they might lead enemies back to their people.

Gentle Advisors. All are welcome in a lobsteronian community. Intelligent, empathetic, and patient, loberstonians make excellent councilors, negotiators, and even interrogators. They enjoy learning and are happy to share the lore they’ve picked up over the years. Outsiders seeking lobsteronian skills or knowledge often find the aliens willing to trade for a service, such as a guided tour of nearby town, the procurement of an obscure tome, or the defeat of a monster harassing the colony.

Specialized Jobs. Every lobsteronian in a community is assigned a specialized job by a council of planners. All jobs are held in equal regard including the council. Cooks, warriors, and farmers are all important in the eyes of the community.
