Justice, honour and Satanus.

Satanus, a loyalist Night Lord who at the end of the heresy wanted no part of neither Chaos nor the Imperium travels to an untouched world, deleting all records of its existence beforehand. There, he becomes what his father could not. Honourable, heroic and a true herald of justice. He was Satanus, and none could prevent him from maintaining peace and justice.

(Warning, this is written in the second person. For those who do not know, this means that the perspective can change from first and third person. This is gramatically correct before anyone complains, the technique is just uncommonly used due to the difficult nature of writing in second person. If this triggers you, just go. Thanks for reading, more to come.)
