Terraveth Behemoth (Reptiloburrowus colossalus)

Alias: None
Origin: Inland Thazvaar (deserts)

The Terraveth Behemoth is a colossal, bipedal reptilian species native to the deep deserts of Inland Thazvaar. Known for its unpredictable surfacing and catastrophic terrain disruption, this creature is one of the most feared entities in the region’s history. Weighing over 90,000 tonnes and standing more than 50 meters tall when upright, the behemoth uses its immense claws and subterranean mass to tear through desert strata, reshaping ecosystems and settlements alike.

Terrain

Burrows deep within the sandy sublayers of Inland Thazvaar’s deserts. Absent in surface settlements or humid biomes.

Lifespan

Lives 200–300 years. Matures at 50–60 years. Reproduction is rare and occurs in deep, isolated burrows.

Height & Mass

Stands over 50 meters tall when bipedal. Adult mass exceeds 90,000 tonnes. Juveniles (under 50 years) are estimated between 10–20 meters.

Uses

• Ecological Role: Disrupts and reshapes desert soil layers; creates secondary habitats but also causes catastrophic terrain shifts and collapses.
• Cultural Significance: Feared in Thazvaari lore as agents of destruction. The leveling of Terraveth—8,000 years before modern Geba—was attributed to these creatures after their eggs were disturbed.
• Guidance: Never disturb or transport eggs. Avoid burrow zones and evacuate during seismic anomalies. All study must be remote and indirect.

Notes

Known from Thazvaari Dominion records dating back 8,000 years, the Terraveth Behemoths are credited with leveling the ancient city of Terraveth. Their emergence followed the illicit trade and hatching of stolen eggs, whose disturbance drew adult behemoths to the city. Extant but elusive, they remain the ultimate symbol of untamed, retaliatory force in desert biomes.
