Slipped

"My father has shown me the way. I merely needed to get slipped on Margrum and have the chat we should have a long time ago. Come, the tower of Bendali is this way." - Sevu before his entire party disappeared.

When someone ingests raw Margrum Root, they experience a lengthy time of drug induced stupor. During this time the person is considered to be Slipped and is generally not responsive to any kind of stimuli. The individuals eyes glaze over and their entire body becomes limp
The experience of eating it raw is said to first send one into a euphoric place where only calm exists. This quickly fades into a dream like state where one communes with their ancestors. This can last for hours or even day depending on the temperament of the ancients and of the one who has slipped.
There is a significant amount of debate over whether this is merely a drug induced hallucination or an actual communion. Many cultures and religions have chosen one or the other when it applies and there has been significant anecdotal evidence. Those who are slipped experience time differently than those outside and often believe that years have progressed when they wake up hours later.
Not all slips are good. Bad slips which can drop people into hellscapes where those they would have communed with are dead or being pulled apart by devils and apparitions. Many return from these slips having witnessed their fathers murdered time and time again.
For the Kichwa, in whose native land this plants grow naturally, many cultural traditions that revolve around slipping. The primary ritual of entering adulthood uses slipping. It is also common for elderly to spend their painful last years in enteral slips. Many Kichwa potions have some refined Margrum Root which provides an effect known as a Slip Echo making the one who ingests it feel euphoric in addition to the original properties of the potion. This can be disconcerting initially.
