Due to their elastic bodies, endiffians can change their appearances at a cellular level and modify individual cells to absorb or reflect light, producing a wide variety of colours; because of this, endiffians can take the shape of nearly any appropriately-sized humanoid, or mould their hands to suit any purpose.
The flesh of old endiffians turn pale and brittle, cracks forming on the most frequently-reshaped portions. The average endiffian is 6 feet tall and weighs 280 pounds.
Endiffians often become subterfuge operatives, pursuing their own schemes at the same time. Mischievous ones enjoy taking the form of reptoids, stirring anxiety about them as a distraction from the endiffian's plots. Old endiffians usually take pride in the latticework on their skin; those lacking them can easily find work as a diplomat or adviser.
