All members of the Shadow Weavers Guild must master the art of making their prophets obscure. No self-respecting shadow weaver may ever be seen to be in the direct line of sight. A well-timed swoop into the nearest shadowy crevice is de rigueur.
All members are required to attend the weekly meetings, held in the abandoned windmill on the outskirts of town, where the great Shadow King himself once dwelled. Attendance is mandatory, and any failure to do so will result in being forced to weave a 100-foot-long shadowy tapestry of despair.
Furthermore, all members are expected to keep a stash of 3-day-old moldy bread in their workstations. This is not a suggestion, but a requirement.
