There can be no other explanation for me sending Spenlow on a seemingly pre-destined journey to An Underworld where he can charm Guardian Creatures with his Other Worldly Musical Abilities. Currently, frankly bizarre creatures and animal familars (including telepathic glowing fish) armed with Symbols of Immense Antiquity and possessing deep arcane knowledge are unerringly guiding his path.
And now, he's off down that hole. It looks like Seth the bat, at least, is going with him but that cricket's disappeared and he hasn't seen his dog for ages.
