1. Yes and no. The majority of the fallen Kells are dead however prime servitors are still around and are easier to make than ever 2. The houses are either extinct or near extinction. After the Siva crisis many of the fallen houses were completely and utterly damaged beyond repair, so they formed the house of dusk together with aid of the house of kings I believe. However some stubborn traditionalists still wear their house colours in defiance. [spoiler]fun fact: remember the first mission of D2 where we're flying back to the city from the mountains? We found out in that yearly summer event with all the gold armor we were actually checking on a crew of house winters fallen [/spoiler] 3. Well all the leadership has changed really, only knew houses still have their leaders. Mithrax has become the Kell of the house of light, Variks has declared himself Kell of Kells and is rebuilding house judgment, and Eramis is rebuilding house devils 4. Same as always, too big to die but too small to live. At this point it's less of a house and more of a club, "if you're wearing the symbol I won't attack you" and all that. Basically the house of dusk are just a bunch of pirate crews who follow the strongest Capitan in the area 5. Maybe? But it might also be Mithrax, who knows

1: All dismantled and ''united'' under House Dusk. Kaliks Prime: Unknown Simiks Prime: Unknown Taniks: Unknown 2: Mithrax (House Light) Variks (House Judgement and self proclaimed Kell of Kells) Eramis (House Devils, Former Devils Baroness, and currently suspected Kell of House Devils) Spider (Mercenary Org) 3: House Dusk was made out of desperation as most Fallen Leadership was executed by us or ''Took" by Oryx. Currently suspected to have a council as leadership. It's mostly an every Eliksni for themselves type of scenario though. 4: Variks proclaimed himself as Kell of Kells, like Skolas before him, it's not official.

The biggest question is whether Taniks ever got some accommodation sorted or is he still homeless???
