Leaving hometown and innocence behind, David traveled to distant lands by Ship, by Sky, and by Mind.
He returned with dangerous ideas, strange powder that explodes, and broken hearts (some parts of others' got mixed in with his own). He keeps most of it locked in a wooden chest preserved with tar and strengthened with iron bands and padlocks.
The people in his village give him strange looks - travel has been both kind and cruel to the social outsider.
When he returned to fight in the Great War, he found that up until then he was a puppet in a diabolical plan to defeat true justice.
Now a double agent - he travels to multiple dimensions, foreign lands, and other worlds using wits, fists, and technological gadgets to collapse the Overlord's organization from within. Oh, and lasers - don't forget about the lasers.
David is a believer in the Christian faith, which often acts as a guide in determining which tales are worth telling.
