It's Archaeology

Last session, the continued looting the tombs at the war memorial. After the armor set found on Zhang's body, the party also found some magical crystals within Mo'o's sarcophagus. However, when the party attempted to loot Simone Bolivar's casket, the tomb came to life and attacked the party.

The party had to fight off the reanimated body of Zhang, an elemental from Mo'o's coffin and finally an coffin automaton that holds Simone's body. The party defeated all of them and realized that Simone's body was missing from the sarcophagus. Instead, the party finds a crystal in its place.
