Crafted Races become sentient

Cultural event

In the wake of the Giant's disapperance, their Drones are forced to adapt to a world without guidance, many simply break down without direction or maintenance, but the inherent instinct to survive found in organic life starts to motivate the sophisticated constructs into making their own decisions. This culminates in most varieties of Crafted independently developing self-awareness and band together not just between their own groupings, but as a collective of all artificial life.
