The streets of the southeastern city of Osibu  are literally paved with gold. Located in the Screaming Jungle within the greater Mwangi Expanse, the city is protected by a ring of statues called the Circle of Twice-Honored Women, which somehow reduces the cacophony of noise from the jungle and also keeps out the jungle's carnivorous plant life.
The city is a democracy, and life is a veritable utopia for its inhabitants. There are plentiful supplies of fruit and water, and the city's wise-women are able to mix rare herbs to produce an ointment which greatly extends life and staves off diseases.
Osibu is home to possibly Golarion's oldest living creature, the hunched arboreal regent Dimari-Diji, Final Tree of the Elder World. The ancient arboreal regent's first memory is the coming of the Starstone nearly ten thousand years ago. Dimari-Diji guards the Nemesis Well, a way between worlds. Pathfinder Durvin Gest famously dropped the Lens of Galundari into the Well in 4332 AR.
