Alright, my Grumpy Garys, trying to stay try true to Pixy's original design while keeping in mind the concerns of a certain Gemini of the Dark variety, as well as my own wishes and original designs, I came up with this:
Power (RED) - The red psion focuses on unleashing their energy in the most direct way possible, i.e., using it in the form of direct force and power. These psions focus on generating energy externally and then unleashing it all at once. Powers in this category usually focus on destructive attacks.
Control (BLUE) - The blue psion focuses an the internalization of their energy before its use. The use the energy in a calmer, more relaxed form, focused on obtaining control of how their energy will be used before it is released. The abilities don't have the raw power of red's, but they a more direct and precise. Powers in this category usually focus on manipulative attacks.
Wisdom (YELLOW) - The yellow psion focuses on the more less direct manner in which their powers can be used, less on how they can effect others directly, and more on how they can use their abilities wisely, as well as benefit the user. What they lack in their ability to directly harm the opponent, their strength, and their control, they generally make up for in how they end up benefiting the user and slowing down the opponent. Powers in this category usually focus more on projection of energy as opposed to directly hitting the opponent.
Power through Control (PURPLE) - The purple psion sacrifices some of the pure destructive power of their attacks for more precision on how their abilities. Powers in this usually category focus more on calculated damage to foes.
Control with Wisdom (GREEN) - The green psion has combined their control over their energy and their focus on beneficial abilities to focus almost exclusively on helpful abilities. Powers in this category usually focus purely on beneficial for the user and those around them.
Wise use of Power (ORANGE) - By focusing their wisdom more on fending off the opponent, the orange psion is able to directly harm the opponent in more careful ways that better use their energy. Powers in this category usually cause damage that have more lasting effects on enemies should they survive.
Each Psion usually falls into one category. The can blend into other categories, but it takes a deal of strength and effort to use an ability outside of your color correlating to how far away from you move. So a blue pisionic can use green and purple with some effort, red and yellow with a great deal of effort, and orange would be incredibly tasking and likely dangerous to attempt.
Powers (In no direct particular order):
Red - Psi Lance, Pyro-Conjuring, Telekinesis
Blue - Mind Fray, ESP, Physical Enhancement
Yellow - Telemagery, Telekinetic Field
Purple - Psi, Neural Feedback, Mind Control, Mind-Merge
Green - Biokinesis, Imbuing, Psi Inspiration
Orange - Rift, Psi Panic, Telekinesis
And I realize this isn't perfect, on there on some abilities that some of you might not feel fit, but... what can I say? Not perfect, and can't please everyone, but I'm happy with this. And Finally:
Ascension (WHITE) - The ultimate goal of the Ethereals is to find/produce one who can ultimately embrace the gift in its fullest, the Ascended Psion. Evern amongst the like-minded alien leaders there are disagreements about the white psion. So believe they are looking for a specific species, while others believe they are looking for a specific individual, independent of their race. Some believe once a species fails to embrace it, it never will, while other believe there is always hope it will be found (including by the Ethereals themselves). Some believe they will find it naturally, while others believe it will have to be forced out. Some believe it my require more power then one can handle in a physical form, and amongst them, some believe finding it will immediately destroy that being, and they will only be granted a brief glimpse into that power, while others believe the one who obtains it will ascend to a non-physical form. Some believe the white psion will be able to use all the abilities of the others, some believe they will have abilities all their own, and some believe that both are true. Regardless of their beliefs, the Ethereals strive to lead others on "The Path", help them (or force them) to embrace the gift, and hopefully, in the end, find one who will Ascend. In the end, it is a search for more then just power. It is a search for God himself.
