@Kupo: It's a bit more complicated. Liquid Cardamine does of course require the substance to produce but the exact method it is made is unknown at the moment. Bit by bit it'll be revealed in due time, keep your tabs on RP communications and story forum channels. So for now all you can do is to theorize on it's origin, purpose and what it can do.
@Violet.Lotus: few bits explained in Nomad lore. However there is no saying how exactly to RP when you meet a one - it is up to you, a player, to think of what your character would do. There are various ways, but feel free to improvise, just never forget the consequences. Extra caution is advised - don't expect Nomads to act according to your logic.
