Astronomican transmit one powerful psychic signal from Terra spanning 70,000 light years making Warp travel to Imperium of Man possible. Only downsides: It needs Emperor of mankind and thousands of psyker lifes to work and also acts as Tyranid magnet. Device on Sotha what is called Pharos works same way and works with empathic power instead psychic energy and also its signal works even during warp storms. What if the Astronomican was replaced by Pharos devices assuming Imperium would have found a way to create more of them?
