 * In 2168, Erika Hernandez embedded a Fibonacci sequence in a SOS message she attempted to broadcast from New Erigol, where she had been held against her will by the Caeliar for several hundred years . The inclusion of the sequence was done presumably to indicate that the message was not a naturally occurring phenomenon, but an intentional call for help from an intelligent being.
