After the geth secure a location, they round up and impale dead and living bodies on mechanical spikes. The spiked rapidly transform these victims into withered husks, extracting water and trace minerals and replacing them with cybernetics.
The cybernetics re-amomate the lifesless flesh and tissue, transforming the bodies into mindless killing machines. Some alliance soldiers refer to husk- generating as Dragon's teeth, a reference to the mythological beserkers who sprang up from the earth wherever the teeth of the dragon Ares were Planted.
Dragons' teeth and husks bear little resemblance to other pieces of geth technology. No on is sure why a synthetic race woul bother to drain the miniscule amount ofrecoverable rescources from organic corpses, though the value of reuisng them as shock troops is obvious.
