According to the paragraph below, what is the relationship between Dungeon Master and Venger?

Throughout the series, a connection is suggested between Dungeon Master and Venger. At the end of the episode "The Dragon's Graveyard", Dungeon Master calls Venger "my son". The final unproduced episode "Requiem" would have confirmed that Venger is the Dungeon Master's corrupted son (making Kareena the sister of Venger and the daughter of Dungeon Master), redeemed Venger (giving those trapped in the realm their freedom), and ended on a cliffhanger where the six children could finally return home or deal with evil that still existed in the realm.

Venger is Dungeon Master's son.
