If creating a series of comics, what overarching narrative could tie together the interactions between Alphabet Lore and Numberblocks?

An overarching narrative could center around a mysterious 'blank page' that is disrupting both the Alphabet World and Numberland. The letters are becoming more erratic, and the Numberblocks' formations are unstable. The two groups must learn to cooperate, combining their unique skills to understand the source of the disruption and restore balance to both worlds. This provides a long-term goal and allows for exploration of both universes.
