I just thought you'd been working on those long promised illustrations of Hal and Luke fighting off a zombie apocalypse with young hunter Van Hellspawn.
Backstory: After eating a dimensionaly unstable spider, the young hunter gained the power to transform into a flaming demon cat from hell, while still maintaining his sociable demeanor. This, however, had lain dormant in his system until now. Whatever constituted the custard contributed to a catalytic cacophony of chromosomal coalignment, transforming him into what Luke has now dubbed him, Van Hellspawn.
After extensive testing, Hal has discovered the spider had survived falling through Tara's dimensional vortex only to be pounced upon and eaten by the young hunter moment's later. However, the instability of this new transformation is slowly deteriorating the young hunter's frontal cortex, causing him to revert more to his primal characteristics and overwriting the compassion and reasoning of their young friend. Before too long, he will be only Van Hellspawn and nothing more. A voracious demonic beast bent on the destruction of all life in the universe. It's like Mad Cow disease, but for cats who've eaten dimensionally unstable spiders.
This is why they've dared to violate the Proscribed Planets Dictum and landed on Earth #000,000,666, otherwise known as Hell. A timeline where the demonic gateway was opened by Galileo in 1633, unleashing the incalculable evil long sealed beneath the Vatican. The land is barren, burnt, and wholly hostile. As they've discovered, undead roam the surface in herds thousands upon thousands while their vampire overlords scheme to escape the bounds of this single world, this timeline, in their quest to bring death and destruction upon all of them.
Now, only Hal, Luke, and Van Hellspawn stand between the hordes of darkness and destruction of all life in every timeline. Granted, the threat wouldn't have happened had they not landed the Tardis on a Proscribed Planet, but none of them knew any better when Tara, still addled by a spider falling through her dimensional vortex, suggested it as a solution to the young hunter's dire prognosis.
Thus, our heroes are once again saving the universe from themselves, one mistake at a time!
So, no worries about the delay. We've been looking forward to this story arc.
