"My ship has a large number of ways to detect things. You'll learn about most of them if you read the entire library I gave you. It can detect weight, it can detect any heat you give off, it can detect the patterns of air left when you fly, it can detect subtle changes in the air you breathe out, it can detect you by the fact that there's not as much air in the space you're occupying than around you... And so on and so forth. I want to make a list of what stuff I have that can find a sorcerer when she's trying to hide."
