Primal Evolution: Stone Age Isekai

An Isekai survival and civilization-building campaign set in a harsh, prehistoric Stone Age. A modern human is transported into a primeval world populated by distinct Beastkin tribes. The world is brutal, ruled by megafauna, extreme weather, and scarce resources. With zero magic and only primitive technology available, the protagonist must rely on real-world scientific knowledge, strategy, and resource management to survive and slowly drive the technological evolution of these tribes.

Welcome to Primeval Age — an uncompromising, hardball survival RPG and evolutionary sandbox set in a brutal stone-age world. 🔥 WHAT TO EXPECT: • Unforgiving Survival: Rigid tracking of hunger, thirst, physical stamina, and labor fatigue. Every action has a physical weight and dynamic time cost. • Authentic Beastkin Lore: 100 unique tribal NPCs across 5 distinct species (Wolffolk, Catfolk, Merfolk, Birdfolk, and Rabbit-kin) with detailed kemonomimi anatomy, culture, and individual personalities. • Engineering & Realism: No instant crafting or single-turn miracles. Complex technological leaps (like smelting bronze) require multi-stage resource gathering, infrastructure, and high dice rolls. • Social Friction & Roleplay: Primitive tribes operate on strict clan instincts, scent, and deep suspicion. Outsiders—whether a foreign Beastkin or an Isekai Human—must earn trust through high-DC social hurdles and actions. Speak carefully: dropping modern academic jargon will alienate stone-age minds! ⚡ ALPHA STATUS & FEEDBACK:This campaign is currently in Alpha Testing.
