The discussion about the rift crossing the city is actually quite popular on the forums.
Many newcomers who haven't experienced the Cardman City disaster are guessing what might be below, and there are those fearless enough to have actually jumped down. Regrettably, the dense Star Realm aura obscures observation and perception, reducing visibility at the bottom of the rift to less than half a meter. Plus, there's the severe negative condition of Star Realm erosion that makes it impossible for newcomers to last very long.
But players who have jumped down are convinced there's definitely something in the chasm, and little by little, this rift has become Crimson Castle's "urban legend".
However, experience has shown that urban legends are really unreliable in most cases!
"I've been spinning around here for half an hour, and there's nothing but stones that have turned purple due to contamination by the Star Realm aura!"
