Yewberry juice is said to be variably poisonous to all Fae. Trick puts into the machine a sprig that looks very much like Taxus baccata , English Yew. Almost all parts of the yew tree contain lethal cardiotoxins; the yew is famously deadly because a few needles or just three seeds can kill a human. However, the bright red berries (actually arils) are the only perfctly safe and non-toxic part of this tree, again..to humans.
Title name comes from the band Rage Against the Machine
Landlady, choose a card. The "Wanderer" card is painted reminiscent of the Rider Tarot deck, but there is no Wanderer in that deck. The Wildwood deck differs greatly from the classic and contains a Major Arcana Wanderer. There is a "Wanderer Tarot" deck, but that is a crudely drawn, uber-feminist, gynocenric / phalophobic rewrite containing none of the traditional components.
The art on The Wanderer card is inspired by the painting Wanderer above the Sea of Fog by Caspar David Friedrich.
