Nirvana

Nirvana is the Neutral Good plane of the Pathfinder Great Beyond cosmology.

It is the plane of ultimate goodness, unconcerned by matters of law or chaos. It is believed to hold the secrets to enlightenment and greater states of being. Therefore it is a tranquil place of peace and purity.

It has parallels with both Elysium and Beastlands of the D&D Great Wheel cosmology, and is often referred to as the Great Wilderness.

Locations

The landscape is typically that of idylic and untouched wilderness; full of fields, forests, oceans, mountains, and valleys all appropriate to the beast-like celestials and petitioners who inhabit the realm.

The "Sun" of the realm is called Everlight which exists as the personal domain of Sarenrae. Within her palace no lies can be spoken and no violent thought can exist, it is literally impossible for them to do so within her established reality, and any attempt to circumvent this automatically bars them from entry.

A valley belonging to Shelyn called Blossomheart exists as an open air garden and studio; a place to create and celebrate beauty. Some gardens can only be entered through the realization of the theme being presented in other gardens, and only Shelyn herself along with two others have managed to reach the innermost garden.

This is not to say that civilisation does not exist here. The city of High Ninshabur is considered to be the heart of the plane, and is so large that it can be seen from most vantage points in the immeasurable landscape. Some of the city is actually the mortal city of "Ninshabur" that was teleported in the midst of its destruction on the material plane, though its inhabitants were spared the memories of the devastation. The city itself is guarded by a police force of Peris, repentant fire angels, who always seek peaceful resolutions to despites, no matter the cost.

Another city called Llourith is referred to as the City of the Angelic Host and is exclusively celestials-only. It is used as a stopping point for Agathions, Azatas and Archons to air disputes, strategise and gather and prepare for new undertakings.

Inhabitants

Nirvana is the realm of the Agathions (Pathfinder's version of Guardinals). Because these celestial beings are Neutral in their outlook towards Chaos and Law, they are seldom called to war with evil creatures or feel the urge to explore and experience other realms, therefore they rarely leave their home plane unless summoned directly. That is not to say they never leave, as they will happily do so if they can assist mortals, but those opportunities don't come up that often.

The Petitioners of Nirvana are called The Cleansed and are typically reincarnated into animal bodies, though they retain their intelligence and independence. This allows them to commune fully with the plane and the petitioner animals often become wiser with age. However some petitioners retain their humanoid forms, typically when they are servants of the gods and need to retain shapes appropriate to their function.
