I have a theory about Elder Celstials.
It may have been totally disproven or not, but I'm to lazy to check
And since Elder Scartarr hasn't released yet, I have time to say it before it is proven/disproven.
My theory is that the Elder Celestials in MSM will not match the Celestials in DOF. It may be bold, but I think this because of one main reason:
The Monster Handlers put so much work into introducing new things like how Adult Blasoom is fascinated with the "Middle C Ages" or how Adult Vhamp took "a keen interest in all thing Mythical" and to just throw it all away in the Elder designs?
The designs will mostly stay the same, but with a few big differences. For example, Syncopite's rocks could be gold plated, Atmozz could have bigger hair/fur, or Plixie could just be really jacked.
Maybe the designs could lead more into their personalities. Like Hornacle could be a swashbuckling pirate, Galvana could become a pro athlete, or Torrt could be a beach lover and hippie.
In conclusion, I feel like it would be cool to get total or slight redesigns for the Elder Celestials instead of reusing the designs frim DIF.
