In all forms, they are supposed to lack a shadow, but due to technical issues with A Realm Reborn this has not been consistently portrayed. 'Ascian Prime' is a form similar to the skeletal Ascians, but larger and wearing a mask composed of the two Ascian overlords that combined to form the Prime. In this form, their legs are not visible and they have skeletal bird-like wings. Ascians can also appear in a skeletal form, similar to contemporary representations of the grim reaper, wearing long habits with hoods that cover their heads and faces. Ascian overlords wear red stylized masks while their subordinates wear black masks. Ascians use dark crystals to convert people into host bodies, using them to suit their ends. When they ready for combat, red glyphs appear over their faces. With the exception of Elidibus who wears white, Ascians are generally depicted as wearing black hooded robes with purple markings and silver adornments, such as pauldrons. Materials that absorb aether, such as white auracite, can temporarily trap an Ascian in the mortal plane and a potent enough blast of pure aether can effectively destroy them. Ascian overlords are notoriously difficult to destroy, as their souls can escape to the rift if their mortal body is killed. Possessing new bodies considerably weakens an Ascian, but possessing the same body or a clone does not appear to place the same strain on them. Ascian overlords can possess living beings, shaping the body to suit their needs, whereas lesser Ascians must use the bodies of the deceased and cannot return to the rift if slain. This lets them travel freely through the aetherial rift to other dimensions and allows them to possess mortal bodies to directly interact with the physical world. Lesser Ascians are the weakest and generally unnamed, referred to only by their rank.ДЄscians are immortal aetherial beings as a result of their mastery over a power known as the ' Echo', which allows their souls to maintain their individuality within the aetherial sea instead of dissipating. Members of the Convocation are referred to by their title rather than their true names, these titles are based on the names of the Scions of Light from Ivalice.

Under them are the Ascian overlords, whose souls belonged to the remaining sundered members of the Convocation of Fourteen (the ruling body of ancient Etheirys that summoned Zodiark). The unsundered- Lahabrea, Emet-Selch, and Elidibus-are the most powerful Ascians with the power to recruit others into their group. To aid in this task, the unsundered raise individual fragments of the souls of their ancient colleagues into Ascians. This ' Rejoining' process involves the ultimate destruction of these parallel reflections and all life therein. As the Ascians, they labor to reunite the dimensions to revive Zodiark and restore their lost civilization. Only three ancients, who came to be known as 'the unsundered', survived with their souls intact.

This disaster, caused by the battle between the elder primals Hydaelyn and Zodiark, also divided the souls of all living beings on these shattered reflections. Lahabrea, Elidibus, and Emet-Selch with Zodiark in the background.ДЄscians are the remnants of an ancient race of beings who lived on the planet Etheirys before it was shattered into the Source and its thirteen parallel dimensions in an event known as the sundering.
