Every cycle of this random asteroid I saw once when I was taking a shit outdoors in the night, is the sign that we'll gather for discussions and stuff. It just happens to be that this asteroid is visible every 12 years, so yup that's when we have this meeting.
Blame yourselves for choosing to follow my whims, just cause I happened to be hanging out with my cultivator friends and I was the strongest. You all said let's do this more often then told me to decide when. Now this is just routine even if it's been 700 years since that fateful crap.
