Feyroot

A common drug among the backalley common folk, which is not as strong as the Nightdust but can be more commonly found and can be bought at much cheaper prices.
It causes hallucinogenic effects similar to those of fey magic, hence why it was given it's name. Other than that it calms the nerves and relaxes the body, putting you in a trance-like state.
Possession and use of this drug is illegal in all kingdoms except for Thyren, the home of the Wood Elves. There, Feyroot is used as a medical relaxant, and some more rowdy young-ones take it for entertainment purposes. Though it is not very easy to get a hold of, as you will need a medical prescription from someone with the authority to hand out the drug. It is relatively expensive to make, as some of the ingredients must be harvested in the Feywilds.
