I'm just throwing around some ideas for ardents who belong to factions, since this is the psionic class that gets mantles (up to 6) based on their philosophies. I generally only picked 4, since I believe there should be a bit of room left for other mantles of the players choice
Athar: Knowledge, Planes, Mental Power, Justice
Believers of the Source: Creation, Pain & Suffering, Elements, Fate
Bleak Cabal: Corruption & Madness, Mental Power, Communication, Chaos
Doomguard: Destruction, Consumption, Conflict, Energy
Dustmen: Death, Consumption, Repose, Light & Darkness
Fated: Fate, Physical Power, Consumption, Guardian
Fraternity of Order: Law, Knowledge, Fate, Magic
Free League: Communication, Freedom, Planes, Guardian
Harmonium: Law, Justice, Force, Guardian
Mercykillers (and most likely Sons of Mercy and Sodkillers): Law, Justice, Pain & Suffering, Conflict
Revolutionary League: Deception, Freedom, Justice, Chaos
Sign of One: Creation, Mental Power, Fate, Communication
Society of Sensation: Freedom, Natural World, Planes, Life
Transcendent Order: Mental Power, Physical Power, Conflict, Planes
Xaositects: Chaos, Freedom, Time, Corruption & Madness
Mind's Eye: Mental Power, Knowledge, Freedom, Natural World
Guardians: Good, Guardian, Life, Justice
Primals: Elements, Energy, Planes, Force
Ring-givers: Repose, Pain & Suffering, Life, Creation
I think that Time should also be added to Doomguard and Dustmen, becaouse Time is universal symbol of entropy and life passing.
