Starship Brief

After many years in the Unknown Regions, Darth Mordred came back in need of new weapons and devices. Using the old pass code given by Doriana, he entered the Siennar Fleet Systems main research facility and requested the best prototype they had. Fortunately for him the first prototype for TIE Defender was just being finished. So Mordred ordered a few custom modifications to allow him more flexibility and firepower, leaving the station with the new prototype. 

This 'request' delayed the TIE Defender line production in almost 2 years.
