Isekai Rohan

Einhoren

Royal colosseum 

Walter was spectating the events from within the VIP room. Keeping tabs on the wins and losses of the gladiators down below. The majority of the battles were humans versus monsters that concluded of

[Varg Patriarch] Wolf like creatures that can grow up to be as big as horses.

[Berg] A beast that stands up on two feet, with a bear's head and arms long enough to claw the floor.

[Enchanted Tonken] Blue skinned humanoid beasts who hated the light, they wore anything they could find as helmets to dim the sun. Muscular and tall, they were sentient beings.

The people, the audience and spectators had no idea. This colosseum wasn't built for their entertainment, the true purpose of this establishment is to nurture more strength. This was information privy only to the Royal family and the Royal corps. the common army were ignorant, as so were the peasantry.

Beasts were captured whilst weak, and once they were pitted against and devoured enough humans they evolved to the greater beings. Like the [Varg] that would evolve into [Gray Varge] and then [Varg Patriarch].

It was a known fact for the royals that killing lesser-evolved monsters presented diminishing gains. Hence, the royals willingly built this place to nurture the monsters. Breeding and growing them, sacrificing the people foolish enough to entertain the idea of wealth and fame, challenging the monsters for coin. 

All prisoners and criminals unlucky enough to be captured were presented to the colosseum. 

"For the greater good of Del Lagos. Amen." Walter would repeat.

Once the monsters were at a satisfactory strength. They then would be transported to the Royal training grounds, out of sight of the common rabble where either the Prince himself or his Paladin corps would slay it. Thus, cashing in on the funnelled increment of power and strength.

Personally for Walter, rather than eating these home grown domesticated beasts. He enjoyed diving solo into monster territory. The thrill, the blood bath and adrenaline rush reminded him of his humanity. He truly believed that the human race were destined to stand above all others. 

Walter would devote himself to this Kingdom of man. Even if, another civil war broke out. He was sure, humankind would emerge stronger than before. And then he could finally set his sights towards the south. Towards the elves.
