Seismic Fibrillator Node

A Seismic Fibrillator Node is a potent Tau device that, when activated, emits resonant frequencies of such power that they cause localised earth tremors. When used correctly, the tremors these disc-shaped devices create can be greatly magnified and last an extended period of time. Developed by the Earth Caste scientist O’Vesa at the personal request of Commander Farsight, Seismic Fibrillator Nodes were used to defend the Farsight Enclaves against the assault of Waaagh! Grog. Upon the watery world of Salash’hei, Seismic Fibrillator Nodes placed on the ocean floor to awake the wrath of the world’s oceanic vents, causing tsunamis of such immense size that entire Ork navy was wiped out. Seismic Fibrillator Nodes were also used during the defence of Lub’grahl when a clutch of them where dropped into B’oghal, the Great Abyss. Before the hour was out, every one of the delicate rock spires that covered the world collapsed, burying all of the invading Ork hordes under forty metres of rock.
