On September 21, 1986, a monstrous creature encased in an amber monolith was found buried in Big Sur national park. It was recovered by the government-funded Earth Corps, a geological sciences research team. The finding spurred honest industrialist Blackthorne Shore to clandestinely uncover a second monster buried elsewhere — a giant vine-like creature called Tendril, who attacked the amber block's public unveiling in San Francisco on December 14 to release the macabre colossus trapped within, D'Compose. They rampaged through city streets before fleeing into the watery darkness of the bay.
