Summary:
The Roller-poly is a colossal insect native to the high-altitude peaks of Grafangu. Characterized by its massive size, unique plough-shaped head, and affinity for sulfur, this creature plays a crucial role in the ecological and geological balance of its remote environment. Often traversing the mountainous terrain by rolling around on a giant granite sphere, the Roller-poly at times uses the sphere as a hunting tool.

Basic Description:
The Roller-poly, or Sulfur Burrower, named for its diet and subterranean habits, resembles an enormous beetle with armored plating and a forward-projecting, wedge-like head. Averaging the size of a small car, it uses its robust, scoop-shaped cranium to dig through rock and snow, exposing mineral veins. Its segmented body is coated in a waxy, heat-resistant shell, allowing it to navigate the harsh and acidic conditions of its niche environment.

Rarity: Ultra-Rare

Location:
This insect inhabits the high, wind-scoured ridges and fumarolic slopes of the Grafangu mountain range. These mountains, known for their frequent seismic activity and rich sulfur deposits, provide the ideal setting for the Roller-poly. The creatures are rarely seen below 3,000 meters elevation and are most active during the volcanic seasons when sulfur emissions are at their peak.

Properties:

• Size: Approximately 4 meters long and 2 meters wide
  
• Coloration: Deep slate-gray with yellow striations, helping it blend in with sulfur-coated rocks
  
• Diet: Primarily feeds on crystalline sulfur and other volcanic minerals
  
• Behavior: Solitary, slow-moving, and mostly nocturnal; known to emit a low, rumbling hum while burrowing
