Guardians Trees or Brain Trees
Mainly found in Ejecta Craters around Guardians Ruins areas. On any type of world as long as the world has some form of Volcanism.
An Ejecta Crater can be recognised from orbital cruise. You will see lines coming off of the crater.
The temperature range has to be between 200k up to 470k.
They do drop materials, but only the materials shown on the detailed surface scan of the planet they are on.
To locate a material node on the trees, you will have to look for 1 of 3 things.
Mussidaen Seed Pod (G1-2 Materials)
Polyporous Growth (G3-4 Materials)
Cordycep Growth (G4-5 Materials)
When flying over a Guardians trees area, if you are above 3km from the surface you will see a very very small blue PoI appear on your radar. These PoI are the material nodes that spawn on the trees.
Guardians Trees have also been found in the SKAUDAI Sectors and ETA CARINA Sectors.
Guardians Trees also produce rather a lot of noise. The noise has been described as sounding like Rhubarb thats growing.
