Jernay
From Warhammer 40k - Lexicanum
Jernay is a Princeps of the Legio Ignatum and commander of the Warhound Titan Advensis Primaris during the Taros Campaign. Reporting directly to the Magos Zadakine Volta, Jernay is actually a strict servant of Lords of Mars, so 'god-machines' in the Taros Campaign were not directly controlled by High Command staff of the campaign, but only by Volta and princeps Jernay.[1]
