World Description.

Intris was a world filled with life and a variety of sentient species.

Humans,elves,dwarves,angels,demons and fairies lived in this relatively peaceful world.

But suddenly massive gates appeared in the world as swarms of monters came out from the gates,they battled with the natives of this world and conquered 60% of the lands,strangely enough despite a few of them being sentient they all were hostile with the natives of this world.

Then dungeons too started to appear,these structures are aimed both from the monsters and the natives as those who can obtain the core of the dungeon will become the owner.To obtain the core the challengers needs to complete quests and trials given from the dungeon itself.When finally someone become the owner of a dungeon,they can make it their own house doing whatever they want inside of it.

Then calamities started to appear as well damaging both the monsters and the natives.They rarely appear but the moment they do no one is able to stop it.Thankfully the dwarves were able to build a device able to predict where and when a calamity will appear.

And lastly Systems appeared as they are randomically given from an unknown entity to the inhabitans of this world.There are two kind of systems:the special ones and the normal ones.Special systems grants special privilages and features while the normal ones do not.

After 10 years from the beginning of all,the inhabitants of Intris eventually adapted and guilds,alliances,corporations and even empires were formed.
