Carved out of the sheer rock face of a floating island, Abshah’mal has been a bastion for the Tsekwe and Anlo-Ewe tribes for centuries. Once a site of pilgrimage for ascetics, with time it was built into an extensive collective of stepped spires and spiraling stone pathways. To outsiders the structures appear to be inverted, hanging upside-down from the bedrock overhand, however, such designs were intentional as they were constructed by the avian tribes of Onnen. The platforms and ledges serve as landings for its inhabitants while stairways cut into the rock provide pathways connecting buildings.

The monastery is now under the care of those who still devoutly worship Onnen, the first world tree. The main sanctuary is adorned with carved reliefs and colored mosaics depicting the history of the world, surrounding a large carved piece of petrified wood in the center. The sanctuary floor’s design radiates outward from the sculpture, symbolizing how Onnen was the center of the world. The winds around Abshah’mal Monastery make accessing it no easy feat. Those without flying mounts and guides experienced in navigating these tempestuous currents will have difficulty landing safely.

The entire monastery is self-sufficient, growing food and medicinal plants within indoor greenhouses tended by the monks. These greenhouses are structured around a central opening in the roof acting as a skylight, while plants are grown in tiered rows carved into the walls. Sunlight and rainwater enter through the skylight while the plants are otherwise protected from strong winds buffeting the island. Rainwater is conserved and stored for dry months through collection channels carved into the greenhouse floors. These channels drain into a rainwater reservoir which provides Abshah'mal with its fresh water. During colder months, clear coverings are placed over the skylights to keep the heat in.

The resident monks are vegetarian, though they occasionally partake of fish when trading with the locals of the lakes below. They trade handicrafts made in the monastery for what they cannot make themselves.

Deep within the stone halls of the monastery lies the Hidden Sanctum, a secret place that not even most of the monks know of. Monks who become caretakers of the hidden sanctum undergo a procedure of rigorous trials conducted by the monastery’s elders. Those who pass the trials are then set apart from the rest to devote their lives towards protecting the sanctum. Within a hidden portion of the sanctuary, a great sapling of the world tree resides out of sight from the world. This is a sacred place, and only caretakers are able to enter. A powerful force repulses those who have not been ordained as caretakers from setting foot within the sanctum grounds.

The roots of the sapling of the world tree are surrounded by channels carved into the floor radiating out to the edges of the sanctum. Within the channels there are ancient symbols that only the monks can decipher. On the walls there are hand-painted murals depicting the creation of the world, mirroring imagery seen in the cathedral of Zets'Ki. The overarching symbol of Onnen, the first world tree ties together the entire chamber. Materials from different parts of the continent have been incorporated into the artwork, representing unity of all the peoples of Onnen.
