So the next time your Devourer rejects a perfectly good Zombie because it “wanted a Skeleton instead,” just sigh. That’s not a bug. That’s sibling rivalry.

This dynamic creates a gameplay echo of sibling rivalry: the Keeper offers risky, powerful, forbidden trades (like the relic), while the Grimoire pushes slow, steady, “respectable” growth. Choosing between them feels like choosing between a rebellious sibling and a sanctimonious one.

| Mechanic | Sibling Rivalry Interpretation | | :--- | :--- | | | The Devourer (younger sibling) screams “I want THAT!” forcing you to ignore your own merge plans. | | Keeper vs. Merchant | The Merchant (safe, boring, approved by the Grimoire) vs. the Keeper (shady, rewarding, exiled sibling). Choosing one angers the other. | | The Time Machine (Prestige) | Every time you restart, you leave behind a “shade” of your previous run. That shade acts like a smug older sibling’s high score. | | Rival Merges | Merging a Lich and a Gorgon triggers special flavor text: “They never got along in life. Death hasn’t improved things.” |
