Spelljammer Is Shatterspace the 5e equivalent of the Astromundi Cluster?

[Matt Adler]

In all

To be honest, I never cared about the World breaker because it was actually the sub plot. I was more interested in the main Axia/Blacktongue plot. Also most of the characters didn't even really care about world breaker as their motives were just simple "I want money".

That's a fair take, but it was suggested ever since the discovery at the vault that they (and Blacktongue and Shard) thought there might be money to be made in discovering Worldbreaker. To have all of that end in finding absolutely nothing, not just in terms of wealth but even any answers about the mysteries teased, feels like a cop out to me. I may have felt differently if the Axia/Blacktongue reveal had thrown me for a loop, but it was one of the first things I considered when Kori shared what her divinations revealed about Blacktongue... and it's also the M.O. of a well-known Forgotten Realms villain.

Side note, I thought it would have made Axia a more interesting character going forward if the sword she found in the temple had retained it's, um, unique personality

If you replace "world breaker" with "plot hook" in that sentence, you could be describing far too many of the PCs I've DMed for over the years
