Soulsense, also called Inner Eye, ESP etc. is an ability to spot living beings through mystical means. It is coded as SENSE, and allows one to see through darkness, smoke and even walls, up to stated range. Naturally, the Star Gods and their magic are known for powerful SENSE, however, some monsters might possess supernatural sense of smell or vibration, or whatever, which also counts as SENSE. Note that SENSE doesn't allow spotting non-sentient beings, like normal robots or droids.
