A river of liquid shadow snakes a treacherous path through the darkest parts of the mountains to Po-Nu-Ov-Ba wahi, where it dissolves under the fierce light. If one were to trek the many miles to it's source, they would find a cavern full of ore that amplifies the pitch black darkness into a river of shadow.
A skakdi of shadow leaps into the river, basking in the refreshing darkness. The skakdi of psionics on the bank is content to simply watch and not have his legs burnt off.
Saorn, the skakdi of shadow, absorbs the shadow as energy, becoming stronger and stronger. After much travel, the two skakdi reach the actual cavern. They set up a small outpost beside the opening.
Rahkshi of fragmentation dam the river... A lake of raw, undiluted shadow begins to form, hindered in no way by the occasional rahkshi of darkness.
The dam's leaks are sealed using molten rock, formed by Plasma. Underground, ten rahkshi of molecular disruption prepare tunnels to route the darkness elsewhere. Rahkshi of darkness are posted to maintain and intensify the purity of the shadow in the pool.
21 kraata of adaptation are teleported to the area to begin accumulating adaptations. They are immersed in the extremely raw shadow and gain the ability to sponge up darkness/shadow and use it as physical energy...
