@Durin, I'd like to ask about the canonicity of some of the stuff from the book Rites of Passage, which is about a navigator having to deal with politics, murders, and the disappearance of an entire world. You can find more detailed info on it
here and
here if you want but you don't really have to look at it. Anyway, in the book, there's a Chaos agent who discovers a ritual to tear open a hole in reality and attract a giant daemon, one big enough to swallow an entire planet according to Remleiz (I suspect that's an exaggeration, but it's certainly massive). The daemon uses the ritual to drag an entire planet into the Warp and eat the souls of its people. Part of why this is possible is that the ritual only lasts long enough for the daemon to eat the planet, and part of it is the sacrifice of 8 Navigators and the usage of their warp eyes in the ritual. (The daemon only has one eye and I have no idea if that's important or not.) The ritual is repeatable and the Chaos agent requires the aid of a Chaos cult on the target planet to pull it off (the cult is unaware what they're getting into.)
1. Is that daemon canon in Embers?
2. If so, does the ritual to summon it exist in Embers?
3. If the ritual does exist, how does it differ from canon if at all?
4. The book says that Navigator feuds are formal, with signed declarations of conflict setting out terms, such as whether violence is allowed or only social/economic stuff, etc. As long as it's non-violent, the Arbites and Planetary Governors don't care. If that was ever the case in Embers, is that still the case in the Imperial Trust?
