Second Extrasolar War

The Second Extrasolar War also known as the Second Helghan War was the second major war between the ISA/UCN and the Helghast.

The war began in 2357 when the Helghan Empire, under the control of Scolar Visari, sought to dramatically expand itself by invading Vekta, then invading Earth once Vekta was conquered, and destroying the UCN. Any opposition from the ISA-controlled systems would be crushed in a subsequent invasion of all other Human colonies.

Invasion of Vekta
The first stage in the Helghast's expansionist plans was the reclamation of the ISA controlled world of Vekta. Initially the ISA suffered massive casualties and territorial losses on Vekta after the Orbital Defence Systems 'malfunctioned', opening up the planet to a mass invasion force, and with a pair of high ranking double agents, the Helghast managed to take large swaths of territory and inflict severe ISA casualties in a savage blitzkrieg.

despite intense and harsh actions of Jan Templar and UCN reinforcements, the invasion succeeded and the Helghast occupied Vekta, leaving only one ship that survived the Earth Fleet's destruction.
