The Grim Sabbath manifests as a tag that seems to absorb light around it, leaving an afterimage of shadow in the wearer's palm. Those who witness its bearer approach report feeling a subtle chill, as if the temperature of the course drops by ten degrees. The tag itself is warm to the touch despite its dark appearance, as if harboring a secret flame that will only ignite when competition begins.

The Grim Sabbath exists as a warning to all who would challenge the hierarchy—some battles are decided before the first disc is thrown. Bearers of this tag are those who have already proven they belong among the elite, and their presence alone forces opponents to question whether they've prepared enough for tonight's contest.
