MindArk offers a gift to all Mentors, everytime their disciples complete the Disciple Period. Zed received a Castorian Combat EnBlade-4 Mentor Edition as a gift for me having completed my Disciple Period. Not happy for giving me that promotion to Sergeant at CSF, Zed offered me this Castorian EnBlade too, as a prize for my achievement.
I offered Zed an Argonaut Skull for her to use as decoration at her appartment. A symbolic gift.
