OK, a few things. A: All the Fallen united under the House of Dusk B: Thanks to a scannable on Titan, we know that they all use variations of the House of Kings encryption C: Uldren controls the Kings Conclusion: The House of Dusk is the United Fallen under the Kings banner... which is now the Reef banner. So why are they still hostile? Also it doesn't say anywhere that Uldren assassinated the Kell of Kings, the card implies that the Kell of Kings let Sov become the Kell. Also that is NOT a House of Judgement symbol... that has bothered me since I scanned it. It is the Fallen symbol, the collective symbol.
