Born again, The Forgotten sword to never let a chance to do good pass by, and by sheer force of will, manipulated the world around him. Taking up arms and armour, laying around him with brutal blows, The Forgotten became a warrior of the people striving to protect them from anything which threatened. His focus was renowned, his wrath terrible, all the while his eyes glowing red

Level 6 - 19

Spoiler

In touch with himself, The Forgotten drew power from the Frozen Hells and the Boiling Abyss, his inherent contradictory nature of good and evil expanding to law and chaos, hot and cold. Attuning himself to these opposing factors, The Forgotten forges himself into a force of true power, shielding with the strong and striking where they are weak, travelling the world writing wrongs where ever he found them. Much time was spent in the frozen north where few could survive for long, the rest deep in the deserts scorching sun boiling water from the very flesh. From the darkest and deepest underdark The Forgotten wandered seeing through the deepest darkness, finding the light and truth, fostering it and bringing peace and freedom to those downtrodden and enslaved

Level 20

Spoiler

Finally at peace with himself, The Forgotten gains divine grace and is willing to die, knowing he has done his best to atone for his previous life. Continuing to walk the world using all four alignments to further the course of good, his blade of balance defies logic legends grow it, surpassing those of himself

The Fun Stuff

Spoiler

So we have a character that can wield the Concordant Greatsword. Well if the Concordant Killer (MM4) could ever let go of it. So we'll just have to go with a +1 Holy Unholy Anarchic Axiomatic greatsword. Then apply Weapon Afrost and Greater Weapon Afire to it, for +4d6 fire and +1d6 cold. Combined with Shock Trooper Power Attack, we got ourselves a decent amount of damage.
Course that is the end result. Before then is your standard shock trooper build, power attacking with a greatsword, or other two handed weapon of your choice.
Alternatively, use of Devil's Aura for minor crowd control, or Heat Death to make something just die.
At low levels, can even play as a Wilder, using Psionic powers. Sure one is chosen as it is required for Cryokineticist, but the others are free to be whatever floats your boat, so 'till level 6, viable tactic.
A rather serious weakness is the low will save, starts of strong but doesn't grow much until level 20, at which point saves aren't a problem any more.
Oh and he is unaffected by three of the word series, only affected by Blasphemy.

Just a mid range shock trooper build with some oddities
