+trait-name-Mk3LoyaltyImplant = Mk3 Loyalty Implant
+trait-description-Mk3LoyaltyImplant =
+    The latest innovation in beligerent employee management, courtesy of Nanotrasen's "Xenos Affairs" research division.
+    The Mk3 Loyalty Implant consists of a series of synthetic-mycotoxin sacs surgically implanted inside the user's lymph nodes.
+    These sacs are biocoded to detonate and disperse their lethal payload once a period of 24 hours have passed.
+    In order to ensure user "Loyalty", a "Delaying Serum" is provided to users at the end of each shift.
