Jonah Maiava tells Lara Croft that Trinity soldiers have seized ancient ruins in the Mission of San Juan area — ruins built for priests of Zipacna and still visited by locals before the occupation. Abigaile Ortiz suspects the disturbance may be connected to the tremors and ash that have not stopped. Lara investigates, finds the Crab Relic among Trinity supplies, and decides to return it to the ancient mechanism it belongs to — walking into a Trinity ambush in the process. She fights clear, restores the relic, and the tremors cease.
