URL updates, my old webhost went down during NS forums downtime.
Description:
"Oasis" is an underground facility under the burning surface of the desert planet called "Dafrik".
Its main task is to supply water and food to people who work in the mines digging phosphorus and other minerals which are then processed in Oasis and used as a power supply.
Phosphorus is being melted and mixed with other matters and the result is a chemical which is reflecting beautiful, pure green light.

Background story:
(Any similarities to actual products or locations are merely coincidental.)
Once upon the time in the Ariadne Arm was a chocolate bar company called "Choconova".
One of the company's factories was in an area which got infected of Kharaa, but production went on because the evil money-grubbing bosses of the company refused to pause the production line and clean up the bacteria.
Chocolate bars were transferred to Oasis among weekly food supplies. When the personnel in Oasis tasted them and noticed they taste somehow spoiled, they dumped all chocolate bars to sewers.
Water pipes clogged up with chocolate and after being long enough in that warm nutritious sewage, Kharaa woke from its dormant state, started to spread and conquer the facility.
Oasis was soon evacuated and TSA was alarmed.
Choconova company was sued and it went bankrupt after paying an insane amount of compensation to Oasis.
Currently TSA is battling to clean up the facility from Kharaa.
