A hexagonal platform between towering pagodas, the entire structure floating in air above the Great Lake, in between Archosaur and City of the Plume, and slightly northeast of Silver Pool. This is the abode of the Celestial One, Celestial Elder, Celestial Recluse, and Celestial Ancient.

The clouds that surround Heaven's Tear, hiding it from view, can be seen as far away as the southwest corner of Archosaur, in General Summer's courtyard

A book describing Heaven's Tear is given by Lady Wu in Silver Pool as part of the Spiritual Cultivation quest chain

Old Heaven's Tear is the first of the time-shifted areas in The Lost Empire quest chain[1] (also known as Chrono Quest chain) that begins at level 70 with the Wraiths' Ploy quest, and is the only such area that can be accessed before level 90

Book description:

The City of Heaven's Tear, also known as the City of Eternity, is another gift from the gods. Bound by thick chains, the city demonstrates the horror of the gods from the Great Flood a long time ago. Some call it the City of Heaven's Tear because, looked at from below, the city looks like a crystal tear. All beings in Perfect World share the same dream: to live in heaven like the gods do. Heaven's Tear, which was left by the gods, has become a trophy in the eyes of many great heroes. Close to two hundred wars have been fought for possession of it in the past three thousand years. Loftia Lake underneath it has been filled with countless bodies. Every full moon, a special crimson light shows up from deep within the lake and dances with the moonlight until morning. That is the Heroes' Blood, one of the Eight Views of Loftia.
