Mercury Alliance

The Mercury Alliance was established after Mercury was attacked by the Beasts and was an alliance of all the nations. They formed large amounts of expedition teams consisting of military and scientific personnel, and went beyond those spatial gateways from where the Beasts came from despite the risks to their lives, looking for a way to thoroughly eliminate the Beasts.

They discovered that killing Beasts in those spatial gateways didn't leave a corpse behind,but there was a certain probability of them turning into a mysterious card called Beast Card.

They became Beastmasters and came back to Mercury to bring peace and stability.

Even so, what surprised them further was that after the Beastmasters successfully killed off the beasts remaining on Mercury, they found out that the beasts left behind corpses now, but never dropped any beast cards.

However, this much was enough for the alliance. With the corpses of the Exotic Beasts, related research could then be conducted. At the very least, the unique materials found on their corpses became some very advanced resources for them.

Just when most people thought that Mercury would finally be at peace, and the various government departments and research units, as well as wealthy corporations, were lamenting that there wouldn't be any more research materials, an endless horde of beasts swarmed out from the spatial gateways once more, ten years after the first attack.

Although there wasn't much difference in the Beasts coming out from the spatial gateways from the first attack, the powerful ones among them could no longer be killed with missiles or other heavy weapons. In the end, they could only rely on the highly competent fighters among the first batch of beastmasters to kill them after suffering heavy casualties.

It was only then that the Mercury Alliance realized the cruelty of the new age. A horde of Exotic Beasts would emerge from the spatial gateways every ten years, and the strengths of the beasts would be greater than the previous swarm.

To the Mercury Alliance, this was both an opportunity and a challenge.
