Your earlier estimation was correct. Three of the larger urns are filled with water, flowers and silver coins, respectively. This is somewhat unusual for a Tamil Hindu tomb, especially one of this age, but not much of this expedition makes a great deal of sense.
Looking in the smaller pots you find, in this order: some mould, some more mould, a bundle of folded white cloth, a small gold ingot, a talisman in the image of Vishnu, even more mould, some mould with a small bird bone in the middle, three engraved diamonds, and a mouse skull, though no sign of the rest of the mouse.
Realising that treasure hoarding can wait until after you complete your investigation, what will you do?
Zing - take a closer look at the walls
Zing - head for the tomb
