Ahriman and Abaddon

[Archaeinox]

So I figured that Ahriman and Abaddon have known each other for a while, and can work together with relative ease. I have exactly 939pts of Demons and I want to be able to swap those Allies out for some Black Legion- Namely, Abaddon, 4 Terminators in a LR and some chosen in a rhino with melta guns.

While not necessarily better than Fateweaver, Flamers, Horrors, Screamers and a Burning chariot, would this be a good move vs. an enemy army with good combat units such as a World Eaters army or balanced Blood Angels?

More importantly, is an allied BL force representative of Ahriman using his Webway knowledge to assist Abaddon in whatever he's interested in for the day?

It'll get you the CTC your looking for that's for sure. But as for knowing one and other yes but they've always focused on there own goals. They'd work together as they both get something out of it.
