This Enduring variation of the standard Entosis Link was developed by the research division of the Capsuleer alliance Affirmative. Affirmative's forces played key parts in the first wave of research into the applications of Entosis technology and were able to optimize the standard Entosis Link for more efficient capacitor use. Originally intended for internal use only, copies of the blueprint have slipped onto the black market and can now be found by those with the right underworld connections.
