Greetings to the dark city!
The Drowned Brotherhood was once a Cadre of the Tau empire, through negotiation and trade with some Kabals you may call friends, or enemies, we managed to establish a presence in the Dark City itself!
While the original goal set out for us by the Empire may have been research of all things warp, and maybe a little reconnaissance, we have learned so much from who we have come to call our dark brothers.
Indeed how can one come to better the greater good, without first bettering oneself.
(So i'm running a Commorragh themed Dark Tau army, should i go project logs or distractions?)
