Vaerik's sharing of credit with Earl Foss had his own considerations.
Before coming to Snow Eagle City, he had pieced together Earl Foss' character from intelligence obtained through the Daily Intelligence System.
Cowardly, vain, severely self-centered, and liked claiming credit without any contribution.
A typical narcissistic personality disorder.
Such people most craved others' praise and feared isolation most.
So rather than letting him scheme behind the scenes, it was better to actively share some military merit while gaining favor and convenience.
Anyway, discerning people could see who really did the work.
More importantly, according to the Northern Province Governor's military assembly order, Snow Peak Prefecture's various forces fell under Fifth Legion coordination.
The Fifth Legion's nominal commander was Earl Foss.
This meant without Duke Edmund's orders, no matter how much merit Vaerik achieved, he'd ultimately fight under this waste's command.
