- "This artifact seemed as though it was made for that unusual lock. Now the door could be opened."
- "This door had been equipped with a singular lock, requiring an unusual key. Somehow I would find it"
When Kain returned to the Sarafan Stronghold in the first chapter of Defiance, he noted a door with an unusually shaped locking mechanism in the 'chapter house' area of the stronghold and he resolved to find the key. By the conclusion of the chapter, Kain had confronted Moebius beneath the stronghold and discovered the unusually shaped Falcon Insignia embedded in a door in Moebius' chamber.
The artifact itself consisted of a golden falcon looking left with wings outstretched. A second bird in a darker shade of brown or grey was positioned behind the first, giving a border around the golden bird. Above the head of the golden bird, the second bird's neck was raised looking upward, giving the impression of it rising above the first.
In the third chapter Pursue Moebius, Kain's initial objectives revolved around the recovery and return of the Falcon Insignia and his first task involved collecting it from Moebius' chamber to open the door and allow him passage to exit the room. Upon returning to the chapter house Kain could place the item in the unusual lock he had seen earlier. This unlocked the Sealed Door behind and allowed him to ascend to the upper levels of the 'chapter house' and 'Sanctuary' areas of the stronghold - ultimately opening the way to the 'relic room' where Kain collected Malek's Shield.
- The Falcon Insignia bears a striking resemblance to the falcon symbols on the banners of the Legions of the Nemesis seen in the First timeline of the Blood Omen era in Blood Omen: Legacy of Kain - set several centuries after Kain's exploit in the stronghold - and may have been deliberately designed as such. Moebius is presumably responsible for its placement and even indirectly comments on the fate of the legions in his chambers before Kain collects the insignia. The symbols were originally designed in Blood Omen to be evocative Nazi Germany and Silicon Knights' developer diary, The Complete Guide To Legacy of Kain, confirms that Adolf Hitler and the Nuremberg rallies influenced Moebius's character and the scene where he rallies William's peasants respectively. Nazism was later drawn upon again to inspire the creation of the revived Sarafan of Blood Omen 2.
