This is what really happens about shangri-la.It is beleieved that there is a land which that leads a supposed portal to argartha.A ancient people were believed to live in this land living off resources around them.This Land is Shangri-la.The natives there were believed to have encounter a very ancient and brilliant race of underground aliens known as the vrilla.The people encountered these aliens and they were at peace.The vrilla offered immortality and eternal youth with the price of mining element 115 for a long amount of time.The people agreed so the treaty began.But then 1 day when richtofen and schousner were testing the first human test subject on the teleporter and richtofen was teleported to Griffen Station.He saw the MTD(or I believed it's called the MPD)He touched it and got a static reaction(This is how the voices richtofen says he hears begin)He is then teleported to shangri-la i'll continue this later on today.
