Drenthal - Geography: The world of Drenthal possessed several areas of ultimate strategic import for any force seeking to maintain or seize control over the planet during the Plague Wars. These included:Agdaen Archipelago - The treacherous shard-coral deserts of these sun-blasted islands are prone to collapsing under extreme weight or concentrated fire, and so the battle for control of this vital strategic location was led by scouts, light vehicles and jump troops that were able to establish safer routes for the heavier war assets that followed. This resulted in a fast-moving, ever-shifting conflict, and control of each of the seven largest islands changed hands numerous times. The skeletons of vast cargo haulers shipwrecked in centuries past dot the deserts of Agdaen, and both sides claimed them as impromptu fortresses, setting up Sentry Guns and fortified emplacements upon their rusted decks. Domination of the archipelago was vital in the war for Drenthal, for it provided a key strategic location for the Chaos forces from which to launch aerial and aquatic raids upon the remaining floating seasteads.Hanghalan Seastead - This colossal floating super-construct is the largest habitation upon Drenthal, home to millions of civilians and a vital Aeronautica Imperialis base. Hanghalen's garrison was forced to fall back to this fortified position under fierce assault from Chaos troops and the unfortunate victims of the Walking Pox, unleashed by Heretic Astartes of the Death Guard. Nearly two-thirds of the city was gutted by firestorm bombardments, and the streets were littered with the skeletons of burned-out vehicles and the charred corpses of the slain. Jump troops and light infantry fought vicious skirmishes amidst those few districts still standing, while columns of armour traded high-explosive shells in the hellish inferno of the arterial thoroughfares.Terebral Station Sigma - Jutting out from the southern polar sea of Drenthal is Terebral Station Sigma, a vast circular platform of steel and rockcrete surrounding an enormous fusion-powered bore-drill. This device extracts priceless lumo-crystals and petrochems from beneath Drenthal's seabed thousands of Terran leagues below, which are then purified in the refinery stations that circle the facility's outer edge. Station Sigma provides the Imperial Navy fighter squadrons of Drenthal with all the fuel they require, making it a vital target for the armies of Chaos. The manufactorum zones of the platform have seen vicious fighting, and around the station the sea burns with spilt oil and toxic leakage. The Imperium had another reason for so fiercely defending Station Sigma; should the war upon Drenthal seem lost, the station's fusion bore-drill could be overcharged, piercing the planetary core and setting off a series of seismic eruptions that would tear the world apart. Although such scorched-earth tactics would seriously hamper the ongoing Imperial war effort in the Konor System, they would deny the Forces of Chaos a significant conquest. Unfortunately, the daemons of Chaos unleashed into the cavernous drill chamber ultimately made this last-ditch plan moot. The servants of the Plague God successfully made Drenthal their own.
