A clever answer.
It basically amounts to no answer at all.
Being "loyal to the St. Hilde family", does not mean loyalty to the currently reigning Duke St. Hilde.
Marquis Garcia is also a member of the St. Hilde family.
In Colin's view, regardless of what finally happens in Ice Rock City.
The master of the North Territory will only be born from the St. Hilde family.
And the key figure in all this is actually Marquis Garcia.
Because the Dark Cavalry, this terrifying army, possesses the force to settle matters once and for all.
Whether they choose to assist the Golden Lion Legion or the Lords' Coalition, the other side will have no chance to resist at all.
Now, it all depends on whether Marquis Garcia chooses to continue being loyal to his elder brother or decides to take up the mantle of ruler of the North Territory himself.
From his previous actions, Marquis Garcia's position seems to lean more towards the latter.
