In my end is my beginning. - T.S. Eliot

This little guy has the disconcerting habit of showing up out of nowhere, dropping almost meaningless clues, then hanging back and letting the kids take care of whatever needed to be done. Yet it's all done for a reason: "All things have a purpose, including your presence here." Pity we never get to find out what that purpose is.

This little demigod seems impervious to extreme heat (walking on hot lava in "Beauty and the Bogbeast") and pain (reclining on thorns in "Valley of the Unicorns"). During "The Time Lost" he walks on water. He gets caught in a crystal in the pilot episode, "In Search of the DungeonMaster", but there's a hint at the end that he let himself be imprisoned so that the kids could liberate the slave mines of Baramor.

There seems to be a master/pupil or father/son relationship between DM and Venger. The two biggest clues there are what DM says at the end of "The Dragon's Graveyard" ("Arise, my son") and at the end of "The Treasure of Tardos" ("There was good in him once, a long time ago. Everyone makes mistakes; Venger was mine.")

Not that DungeonMaster cuts Venger any slack. At the end of "Eye of the Beholder" Hank's bow traps Venger, on his horse, in an energy field. Off the side of the screen comes another energy field, pushing Venger to the far horizon. It's interesting to note that the kids' weapons have energy fields which are characteristically colored. The second energy field in this scene is red. None of the kids' weapons has a red energy field.

DM can't do everything. When Bobby receives a toxic dragon-bite in "The Garden of Zinn", DungeonMaster calls it nature's doing, requiring a cure rather than a spell. Ditto when Eric turns into a bogbeast. Nor are his powers bottomless, as demonstrated in "Dungeon at the Heart of Dawn". This gives us the most human glimpse of DungeonMaster: as an old man who does what he is able, although he is not able to do all things all of the time.

Presumably he engineered that particular car from the Dungeons & Dragons ride to enter the Realm, but we never know to what end. We only hear long after the fact that, when the car arrived, he met with the kids, gave them weapons, identities and instructions that they were to use their magic only defensively. Given all of the above, speculation is still open as to what DungeonMaster wanted to accomplish, and why he needed six young ones, pure at heart, to do it. There has been lots of speculation (fanfic and otherwise) as to how the series was supposed to end. Let us remember that we cannot speculate on the end of this odyssey without also speculating on the beginning.
