Phibinu was the personal maid of the current co-ruling Emperor, just like the other personal maids in the Imperial Palace, unremarkable and indistinguishable.
If she was lucky, perhaps her name would appear in some chronicle or biography; if unlucky, she might die senselessly in a political upheaval.
Of course, more often than not, their names were buried under the sands of history, unknown to anyone.
If there was anything special about Phibinu compared to other maids, it was that she was not from the Danschel Empire but was a maid presented by a vassal state.
In other words, she was regarded by the True Believers as a heathen.
She believed in a pantheon of Divine beings, headlined by the God of Mirrors, which made her somewhat of an outsider in the Imperial Palace.
