The SS Lillun follows the SSV Normandy to a nearby MASS Relay, with their final destination being the citadel. The goal is to meet with the council races and possibly convince them that Obsidian Mask and his crew can possibly turn the tide of battle in the galaxy's favor against the Reapers. Obsidian's fighter follows closely behind in stealth mode. An interesting side note: I scaled the NOrmandy and the LIllun for this scene using their Docking port doors and it turns out that the ships are the same length. The Lillun obviously is much wider and has more upper and lower decks but basically they're both frigates of the similar keel length and roughly the same width. For those interested the Lillun's docking port doors are located the the port and starboard of the ships hull and roughly dead center of the ship's mass in line with the main bridge and behind the main sensor arrays.
