The latest Chryssalid infestation in the Southern Alpines is mostly gone after two weeks of bombardment by Blackmarch's zeppelins and artillery. Thousands of tons of Chryssalid Gas were used; this horrible weapon works by quickening the already overcharged metabolism of these creatures, making them to literally go up in flames or even explode. Officially, the gas is of little danger to normal life, but the Academy disagrees, saying that overdosage can cause mass extinctions of small creatures, thus imbalancing the biosphere, and even, rarely, ignite poorly-shielded Hellerium equipment. Provost Zakharina herself appealed to the international community to condemn Blackmarch military for their overtly brutal actions.
