Pelgrin trees are the generic name given to a common result of the mutagens in Terran Terraforming Probes interacting with a pre-existing biosphere containing high soil magnesium. These trees tend to be tall, willowy and a pale brown or white in colour, with golden yellow leaves.
The bark of Pelgrin trees has a neuro-active effect that quickly refreshes and re-energises the minds of those who consume its extract. Although the extract is relatively simple to produce, it spoils very quickly in air and must be made up by a scientist fresh for each application.
Pelgrin Bark Extract is a type of Exotic Biotic - an Exotic Substance related to Life Science. A physrep of a vial of bark or wood chips can be used to represent a few measures of this substance, but particularly large physreps can hold more. Please do not damage the trees on the sites we are using to hold events.
As with all Exotic Substances, a character with at least 1 rank in the relevant speciality (Life Science in this case) can spend 1 minute of appropriate roleplaying to apply 1 measure of Pelgrin Bark Extract to a character. Tear the Pelgrin Bark Extract card in two to show that it has been used. As Pelgrin Bark Extract does not use a sticker, it does not override any Exotic Substance that is already affecting the target character.
