Acastus Knight-Porphyrion

The Acastus Knight-Porphyrion was a super-heavy war-suit that dwarfed even the mighty Cerastus patterns, a colossal engine that stood at the very apex of Knightly power and bridged the gap between Knight and Titan. Where lesser Knights were champions, the Porphyrion was a walking battery, its twin magna lascannons capable of gutting enemy armour and engines from prodigious range, while a carapace missile array added a storm of explosive fury to its salvos. Layered ion shields and thick adamantium plate let it endure punishment that would fell a Questoris Knight several times over, and its sheer bulk made it a bastion upon the battlefield. Slower and rarer than its smaller kin, the Porphyrion was a treasured relic of the wealthiest houses, deployed to shatter the enemy's heaviest formations and to stand against the god-engines of the Titan Legions themselves. To field a Porphyrion was to bring a house's ultimate might to bear, a war-suit whose firepower could turn the course of a battle and whose presence anchored an entire battle-line.
