Cadia, Kasr Holn and the 13th Black Crusade

[apologist]

While putting together a pack for a 13th Black Crusade/Eye of Terror event later in the year, I've stumbled over a few bits and bobs and wondered if you could help out with some background/lore notes, as (whisper it low) I largely missed out on the Eye of Terror campaign.

The event will focus on Kasr Holn, the fifth planet in the Cadian system. I opted for this as it was a pretty clean slate – but having done some research, I didn't realise quite how clean a slate it was! There's barely anything that I can find which describes the planet.

 

Canonically, it was 'swallowed up by a warp cloud' – but does anyone have any other details, however small, about it? I'm led to understand that the latest release for 10th/11th mentions that there are (post-Cicatrix) embattled Imperial survivors there, but can't verify that. Was there any suggestion on what caused the warpcloud, or who/what was involved?

 

In general, I'd love to hear whether there are any references to specific characters, armies, locations or descriptions of the planet.

For example:

• Is Kasr Holn a Fortress world or something else?
• Do we have any sense of its population?
• What's the climate and atmosphere like?
• Are there any famous figures from here?
• Are there references to battles that have happened here, or with troops from here?

The Cadians will doubtless have a presence on this planet, so I've opted to station two (I believe) new Regiments there: the 136th and 281st (a reference to the White Dwarf issue that announced the original worldwide campaign). 

 

• Firstly, have these Regiment numbers have been referenced anywhere?
• Secondly, are all Cadian Shock Troops specifically from Cadia (i.e. Cadia Prime), or do all planets in the system produce Cadian Shock Troopers?
• Thirdly, would Kasr Holn have its own PDF/Imperial Guard force?

And as for the Chaos forces, I was planning to have one of Abaddon's Chosen spearheading the campaign – while we can make up personalities, I'd prefer to have someone who's both referenced (as a fun Easter egg), and definitely not mentioned as elsewhere at the time.

 

• Ygethmor seemed an option, but I understand that: a) it turns out this is an honorific, rather than a name; and b) Ygethmor fought on Cadia Prime.
• The back-up was Zaraphiston, who I'm sure used to be a 'canon' Sorceror for the Black Legion, but I'm struggling to verify that.
• ... and finally, Sorcerer Lord Xorphas is a third choice.

 

Is there any reason one or other of the listed figures might/might not lead the assault on Kasr Holn?

 

Do you have a better option to lead the assault and conduct a sorcerous ritual to swallow up the planet?

I love including references and Easter eggs in these campaigns, so if there's any tiny little reference, idea or concept that you think might add to the atmosphere, please do share. :)

Thank you in advance for your help!
