Regarding the original topic:
( Nacittal Denorvan) Koro's a native of Mekhios, specifically a city that got
lolpwnt by accident (ty for murdering family, CCP) during the Elder invasion. He was a pretty devoted Sarumite for most of his life, until after a military patrol went down sour during the Covenant withdrawal to Delve and Querious (pre- his capsuleer status) left him mentally, physically and emotionally shattered. After which, post-rehab and capsuleer attaining, he maintained a bit of a hollow attachment to the Empire.
But, after a series of failed, badly-chosen and public relationships combined with bridge-burning and severe mental dependancy on Serena, he's since converted to her faith in the Equilibrium.
While he retains his overall attachment and care for human life, it's been perverted and warped into a desire to save it by exterminating it.
Which is ironic, given the meaning of the name i picked for him.
Nacittal: 11th Sutra, The overcoming of finite limitations and all prejudices, mindsets and misunderstandings that accompany them via the (violent) destruction of one's inner darkness. The attainment of absolute illumination through universal love.
