Hi everyone. So I have been reading over the Tyranid Codex and have started to wonder what GM means Shadow of the Warp to mean. Iv read enough to know it messes with warp travel and Astropath communication, as well as anyone who can use the warp. But does this mean that the Tyranids are a psychic race, and that the hive mind uses the warp to control its brood. Or is this just a byproduct.
So on a similar note, it does not seem that the Ork psychic WAAAAAA is effected by the Shadow of the warp. Which is kinda strange if they both work in the warp. Also would a Hive Tyrant be hurt by a human black, or person who is harmful to warp energy?
Does anyone has any thoughts on this? Specifically what connected the Tyranids have to the warp?
