*Generals side*
The Primus region were mostly occupied by goblins and magic beast.
Not to mention the survival of rank 1, even rank 2 soldiers would have extreme difficulty surviving alone for long given how strong the natives were. It wasn't hard for teams to get wiped out occasionally.
Precisely because of this, it was necessary to have at least 2 of the generals in a place.
The battle with Kirk had thought them a lesson not to underestimate any of their opponents because if not for the reinforcement, Eulise would have ended up dead.
A general might not survive for long in the cruel environment of Primus lands, however, it was a different story when two or more generals joined together as a team to cover each other's weaknesses.
So except for Ashley and Vakal, the dwarves leader the rest of the generals went out to war.
Although the army wasn't as organized as it should be they still did a good job.
