The Trailblaze and Their connection with the stars goes beyond being one Themself. They don't speak to the stars in a literal sense, of course, but rather through shared makeup. When nearby, Akivili can essentially tune into and feel the steady thrum of all those stellar cores beating in tandem, much like Their own. Through this, picking up on disturbances when close enough, and which direction They're stemming from, isn't typically too difficult. If something is wrong with a star, They can tell. Can feel when stars have their lives cut short, snuffed out unexpectedly. When entire star systems are obliterated, leaving nothing in their wake. When galaxies collapse. All that's required is for Them to be within range. If the source behind the cause is destructive enough, hardly any effort is required to hone in on the location. This is ultimately what led Them to Nanook on Their trip to what They believed would be the universe's end, and results in the subsequent events that followed.
