The Astronomicon is a beacon used by Imperial navigators to guide them trough the warp while they are traveling, stretching far across the Galaxy. Its established through pre-existing lore that all psykers are able to hear it, and in some cases non-psykers, such as Captain Gabriel Angelos of the Blood Ravens.

Since Humanity is hardly the only Warp sensitive species, this begs the question. Can non-human Warp sensitive species detect the Astronomican while traveling through the Warp? Couldn't this provide a way for Xenos to find Imperial worlds?
