GPP reactor explosion

The nuclear-reactor catastrophe that created Shard-T during Submine.

The GPP reactor explosion was the event that produced Shard-T during the Submine era. It occurred during the period in which GPP had discovered and begun investigating Tserin.

The incident

Accounts describe a nuclear reactor undergoing an uncontrolled reaction, with its crystals changing before the explosion. GPP's actions led to the disaster, although the precise mechanism and intentions of the people involved remain unclear.

Aftermath

The result was the emergence of anti-Tserin, a red corrupted material later called Shard-T. Its unusual properties, physical invasiveness, and effects on living beings became a lasting danger.

The catastrophe's place in the wider collapse of civilization is not fully understood.
