A recently founded Chapter, the Nightwing's true history is known by only three men: the Chapter Master, the Fabricator General of the Adeptus Mechanicus, and, of course, The Emperor of Mankind. The following are rumours ...
Based on the freezing desert world of Ares Prime, the Nightwings geneseed is derived from the legendary Iron Hands. The founding of the Nightwings was initiated by direct Imperial Edict to the Adeptus Mechanicus. Their remit: to create a chapter for whom technology would no longer be a Dark Art.
These "Scions of Mars" have made war on countless alien-infested worlds, rescuing ancient Human technology and capturing, even reverse engineering, Xeno-tech.
Of course, such close ties to the Adeptus Mechanicus have seen the Nightwings ostracised by other Chapters and Imperial Organisations. They "Stand Alone" in the hostile Galaxy knowing that their wisdom, determination and technology will, in the end, bring vast benefits to the Imperium and rid Humanity of the Xeno threat.
Wise: Scions of Mars
Drawback: We Stand Alone
