Just jumped into the 1000 Episode Fan Art link and grabbed Episode 334, The Final Conflict! I have a solid idea for The Final Conflict fanart entry, and I really hope FotF likes it! I grew up with some of the Odyssey cartoons, but it was the Blackgaard Chronicles that got me into the radio program and made me realize that the world AiO takes place in is much larger than the cartoons suggested. And in my opinion, The Blackgaard Chronicles is about hope and despair: Some of the characters are full of hope (Whit, Jack, Jason, etc), Eugene and Richard are somewhere in the middle given their experiences with forgiveness and redemption, and then there's the arc's namesake, who's full of despair (Blackgaard).
To me, Dr. Blackgaard in The Final Conflict is what you get when despair enters a morally broken soul. He wants eternal life, but without the Jesus part, because that would mean changing himself, and that bothers him more than he lets on. I want my piece to convey that brokenness, not enough to concern FotF and be denied, but just enough to show what despair looks like.
And yeah, I'm probably overthinking this arc to a degree, but whenever I hear Earl Boen's performance in the Final Conflict, the word 'despair' tends to come to mind.
