A heavy, palm-sized seal of brass and crystal. The brass base is engraved with Art Deco sunburst patterns and geometric shamrocks in sharp triangles. The crystal top contains visible veins of liquid gold that slowly circulate, pulsing faster when the Call is active. One face bears the words 'CAPITAL CALL' in sharp, angular brass letters resembling stock certificate typography. The reverse shows a stylized balance scale, perpetually tipped toward uncertainty.

The Capital Call serves as a mandatory challenge mechanism and strategic weapon. When the Ledger detects a player has become illiquid (inactive, avoiding competition, hoarding standing without defending), the Call activates. The player must answer a challenge from any rival who invokes the Call, or their assets are automatically seized. Additionally, any player can invoke the Capital Call on a rival who has been avoiding competition, turning the enforcement mechanism into a weapon. This ensures the market stays liquid and no position is ever truly safe.
