Personal ward generators are usually about the size of a pack of playing cards. Powered by a rechargeable upala battery, they tie into an operator’s prana field and provide protection from extremes of radiant and kinetic energy. There are also models specifically tuned to provide environmental protection as well (for instance, against the cold and dark of the space between worlds), although this greatly diminishes the strength of the field protecting against other damage.
As with many technik miracles, the outcaste and primitive Andhaka lack the subtle energies necessary to successfully interact with these tools, and are forced to rely on mechanical pressure suits (and carapace armor shaped from the brightly colored petals of an exalted flower in the orchid family).
