An extremely easy achievement, travel to Deimos - Cambion Drift. Head down to the nearest river and start looking for slightly flashing trees nearby, called Haptic Fronds. They look like thin and short palm trees but instead of large leaves on top they have three weird branches with pods on the ends. Run up and loot the ganglions they drop when damaged.
Easiest to use an archwing and fly around, but this can be completed as soon as you reach the Drift for the first time.
