Most of the basic information is introduced in the introduction.

Keep in mind that even though it's 2163, nothing has changed much from what it is like today, other than little things such as medicines :p Just to keep things a little more simple

Hybrids in this world are people with animal like abilities. Some hybrids are mutated with animal parts while others look more human with only animalistic abilities.

They are known to human kind as an extinct species after the incident with Dr. Hentri.

Hybrids live in multiple small communities around the world, hidden from humans. There aren't many of them yet, but they still continue to reproduce and further populate their species.

Although they are thought to be extinct, there are skeptics who constantly research and look for these hybrids.

Any other sort of information will be discovered throughout the roleplay :)
