"Mountains occupy considerable space on Adelpha, but this is largely barren". The flora here is reduced to its most basic expression struggling against the ever-present rock, the cold winds and certain extreme phenomena. The most well-known is the "ogor", a plant concretion resembling an ant-hill which often grows alongside lava torrents. The "rase", a grayish fungus growing in the mines in the darkness of the passages, apparently this fungus represents a real danger for the human body. Finally, the extremely rare "edelvia", a flower with silvery highlights said to be luminous and which served in the past to light the way for those venturing into the depths of the mountain.
