I don't know why it reacts this way to you... maybe because you command the stars. But normally, it only glows when my power activates. And it's best if it doesn't activate too much.

[Just like he explained to Song Lan, visions of the future can be a blessing and curse. They come with no context, with little to explain when they will happen, and there is no telling if having seen anything in advance will be useful at all... but mostly, whenever they are significant, it is rarely because they are good.

Not to mention the whole draining of life force aspect, which he hasn't really mentioned. Although of course he also did just claim to have powers even though he said he was human, so make of that what you wish, Runyu.]
