Wall
Wall was a Ta-Ree spell capable of being wielded by Ascendants on the planet Kathol. The spell allowed the caster to erect a physical carrier around themselves, using any present solid material. Depending on the area, this might include dirt, ice, or stone.
The Ascendant could gather material from a ten meter range around them. Less solid materials, such as fire, sand, and water could be used to erect the wall, but it did not last very long.
Ascendants who wished to cast the spell were required to know the psychokinesis spell.
