Saturnine during Great Crusade

[Uprising]

Quick question, as I am eyeing the Saturnine box set due to how cheap it is going for online.  How common was the Saturnine terminator and Saturnine dreadnought during the early great crusade.  I always want to do a small warhound force and wondering if the box is era appropriate.  Thank you and take care.

From what I've read, Saturnine was more common at the beginning of the Crusade than at the end, similar to volkite. Both technologies proved too difficult to maintain, so they became rarer with time.

I think it depends on what strand of lore you want to follow.

 
In the past, the semi-official ‘Saturnine’ lore was that it was largely a pre-Crusade thing that fell out of use as Cataphractii / Tartaros was developed. 
 

Obviously the newer lore is that Vulkan took this ancient design and reworked it to allow it to be better used, then circulated it to the Legions just before Istvaan. The 2.0 rule book also had a timeline of armour development that mentioned Saturnine around as being around during the Crusade, I think. 
 

Personally, I think a Warhounds army using them works. You could even say that, as the suits require the wearer to be psychically attuned, the pre-Butcher’s Nail Warhounds would be more likely to use them than World Eaters.
