Sigil on the van roof

A sigil sits on the roof of the Hangvan, Gorgug's celestial family van, and Fig plays her bass on top of it S3E1·00:07:50 S3E1·00:08:08. Brennan describes the solar lasso as made by the Bad Kids with a sigil capable of capturing the Night Yorb, if it is weakened and pulled within five feet of the sigil S3E1·00:06:45. Adaine's player says she is on top of the van doing the sigil with Fig, so that both have sigil powers S3E1·00:11:58.

The sigil is the trap the Bad Kids built for the Night Yorb, and Fig and Adaine both have sigil powers while riding on the Hangvan's roof S3E1·00:06:45 S3E1·00:11:58. In the fight both of the sigilists are knocked off the van S3E2·00:31:22. When the Night Yorb dies, the sigil morphs into the shape of a manta ray-like monster, an ancient eldritch horror sealed in the roof of Gorgug's van S3E2·00:52:04. Gorgug jokes that it looks like a sick mural, and Brennan agrees S3E2·00:52:20 S3E2·00:52:21. Later Gorgug tells Henry Hopclap that he supposes he sealed the Night Yorb in the sigil, and that he is not sure exactly what happened S3E4·00:49:52.
