Page "Qward" Paragraph 18

All Qwardians now sport slave collars, put on them by Sinestro himself to assure their loyalty.

In addition, Qward had a huge yellow " Central Battery " ( a parallel to Oa's green " Central Battery ") which has since been captured by the GLC and relocated to OA.

Corps members also seem to kill Qwardians for fun and send them armed with overcharged batteries as suicide bombers.
