Level information

Lara has stumbled upon a piece of information about the mysterious sinking of the ship "Selphia" during a voyage in a Southern American lake area in the year 1937. The ship disappeared in an unusual way - the wreck was never found. It was said that onboard the ship a sword with a sapphire-ornamented handle was exhibited. It had been found just a few months before the tragedy, therefore neither its provenance nor its age was ever established, but it was an unusual weapon that would not be used neither by the natives, nor the conquerors from across the ocean. It immediately gave Lara a thought, that the sword may be connected to the mysterious ruins near to the ships supposed resting place. Is the sword a solution to the riddle of these remains? What kind of warrior had used it? Or maybe it is merely an introduction to a much bigger secret?
