Ramblejammed

The cause of the condition is Rambleberries, a plant that is similar to raspberries (like elderberries and blueberries). However these berries contain a condensed form of caffeine ,causing them to affect the people that consume them. The berries are only found in the town of Ulfgar, they are an iconic part of the towns culture.

The condition manifests like energy drinks and espresso. One berry will give you a little more energy, similar to a teaspoon of espresso or Red Bull. However, one glass of the juice can feel like five Red Bulls or seven shots of espresso, depending on how diluted it is.

If one wishes to end this before it wears off, they can drink water and eat bread as it will help dilute and absorb the juice and energy provided by the berry. It will ware off naturally though depending on how much and how diluted it can be anywhere from 10 min to 6 hours of extra energy.

A raccoon folk named Rambleford found a few bushes of them when he was a child, and after trying them he realized what effect it had on him. he picked the rest and planted them in his house garden, and once they grew, he shared them with his town. The town loved it and decided to celebrate a festival the week they were discovered, and named the berries rambleberries after the one who found them.

People love it; it's a staple to eat ramble berries on long workdays, as they give people the energy to get a lot of their work done. They even have a festival for it that people from all over come to experience. They will not export these berries, so this is the only place to find them. They check every single person to leave to make sure no one takes any seeds while they are in town.
