1928 was a year of suppressed internal strife in Rilao. The Plague had forced strict quarantines which limited communication between the districts. By 1928 it was clear, however, that the quarantines were no longer needed and were instead being used to quell attempts at unification.
The PBU flag became a symbol of the public’s desire for unification. Its meaning was derived from the Reo Taion phrase “Pash Bi Unide,” which means “Peace Through Unity.”
Currently, the flag is only available to the viewing public in Rilaoan museums, where it is treated as a symbol of unsuccessful and violent public dissent. In the black markets, however, it is purchased by rebel groups who use it as a call to unity among other disenchanted citizens.
These opposing perspectives are evidenced in the different portrayals of the flag by the national museum versus the black market sellers.
