In a conversation between Brand and Hazram Namir, a fellow member of the Twilight Company, Brand questioned if Namir was judging their captain, "Howl," too harshly; Namir responded by stating that while Howl was a genius, he was also as insane as someone addicted to glimmerstim. The Pyke Syndicate participated in the distribution of glitterstim.
Spice spiders created webs composed entirely of glitterstim.
