Isaac, a blue-skinned Popepi Pipepo, combines five millennia of arrogance, wisdom, and cunning into a diminutive, sharp-minded frame. A silver-tongued salesman and strategist, he first appears caged in a market stall—a calculated deception masking his ownership of the shop and the shopkeeper’s role as his apprentice. Drawn by Sheyenne Rainstorm’s mention of another female Popepi Pipepo, he allies with her and Dr. Kiel Aronnax, pursuing a reunion with his ex-wife, Jerusha.

His history with Jerusha crackles with volatile banter and clashing wills, remnants of their dissolved marriage—one among her several unions. Yet beneath their sparring lies Isaac’s unspoken fondness, their shared past remaining his most cherished memory. Their exchanges teeter between sharp retorts and reluctant camaraderie, hinting at buried emotions neither fully acknowledges.

As the group quests to recover Sheyenne’s lost body, Isaac injects dry wit and shrewd perspectives honed through centuries of schemes and survival. While aiding their mission, his deeper aim orbits Jerusha, seeking to untangle their fractured bond. Millennia of existence have sculpted his outlook into a mosaic of jaded pragmatism, though flickers of tenderness surface when their shared history looms close.
