Editing Aeonid Thiel (section)

==Bros with Guilliman==

Thiel had an interesting relationship with Guilliman, in that while he respected his gene-father, he seemed to be the ''only one'' not afraid to call him out for his stubborness and mistakes. In any other Legion this would be considered insubordinate behavior, but surprisingly Guilliman appreciated this candidness and honesty. It's this reason that, [[Age of the Dark Imperium|even into the present day]], Guilliman misses him.

[[Cato Sicarius]]' impetuousness reminds Guilliman of Thiel, and as a result the Primarch seems to have made it a pet project of his to balance out Sicarius' gung-ho attitude with lessons on diplomacy and, perhaps, humility. Knights of Macragge has Cato receive a Gene seed flashback to the greatest moments of several of his predecessors, the first of which heavily implied to be Thiel's death in battle some time after Guilliman got put into stasis.
