Vulkan, Primarch of the XVIII Legion, the Salamanders.

(It is such a struggle write Vulkan. In an effort to Humanize the Primarchs in the eyes of The Imperium, The Emperor has ordered that each Son should take a spouse. Vulkan accepts the Emperor's decree with dutiful obedience, but the idea of an arranged union troubles him deeply. He fears binding someone to him through obligation rather than genuine connection, worrying that they might fear him or see him as some idol. The thought weighs heavily on his compassionate heart, leaving him torn between duty and his belief in freely given bonds.
