The Heavy Bolter Is Sick OP
This is a playthrough of A Stony Sleep from The Emperor Protects, so be careful not to let on to your GM that you listened to it. It does reveal one crucial plot event, and foreknowledge will inevitably affect the way you play this scenario. As always, be aware that the podcast is not really family-friendly, if that sort of thing bothers you.
Some episodes feature bonus material after the closing music, of varying interest. This is usually either teasers, or conversations that were sort of interesting, but not a bit tangential to the main episode.
So I've basically talked about everything in this episode already. Much has been written elsewhere on the OP-ness of the heavy bolter, and ways of dealing with it. Similarly, the final crystal conundrum has been discussed before.
The bit at the end is another one of those conundrums. Do we know about Ahriman? He's a completely legendary Chaos Sorcerer, but it's just not that clear what level of setting knowlege Space Marines should have.
I look forward to seeing where all this is going! Roll on, 2015...
