How alike are the Tattered Fates adventure and the House of Dust and Ash adventure in Disciples of the Dark Gods? Both seem to feature a countdown to the 13th hour, a Haarlock scion, and a Gilded Widow kinda creature. Is Tattered Fates in any way a bit of a rerun of the adventure in Disciples?

I wanna run Dust & Ash soon but not if it steals all the thunder from Tattered Fates.

Also, does Tattered Fates shed light on a connection between the Haarlock mystery and either the Tyrant Star, or the Slaught?

*spoilers*

You can play the House of Dusk and Ash before or after Tattered Fates and yes they are connected.

The number 13, Widows, Countdown, Clocks etc will be a common theme throughout the Haarlock Trilogy and A&D is more or less a part of it.
