- History and Experiences Which have Affected Character Greatly: Detier Klaus is the son of German Jewish immigrants that escaped to the USA in the months before the second world war broke out. His father served honorably as an army physician in the Pacific theater.
Detier himself is one of the first of the baby boom babies. A result of that joyous reunion in the war's end. He was called to serve in Vietnam as a medic where he met Jerry Saille under less than ideal circumstances. Those circumstances led him to an awareness of something greater in the universe than the mere physical world.
Detier gladly followed his Father into the medical field studying on the GI bill. He entered the pedantic specialty at the close of his residency.
Sometime during his professional years he encounters a spell book that had been dimensionally inverted from Greyhawke. That along with other rare books on the medical profession he collected from various parts of the world, including Tibetan spirit healing, lend him to believe he could harness universal forces to heal. He was right, but oh was he wrong. His attempt to used the forces resulted in the VC-Catz incident and the resulting Mana Storm.
Dr. Klaus is never changed with any crime over the whole matter. He is asked to participate in Bureau 13. He did so as a safe physician.
