In regards to the other Masters if anyone wants an idea of how Cadmus is like as a Servant, he basically gives some heavy JRPG antagonist vibes. Darnic and the concept of the Yggdmillennia family will definitely have him lean towards his "Demon King" persona, treating all the Black Masters as advisors to his rule. He is more than willing to help out the other Masters improve on their magecraft using his conceptual improvement abilities, although most of his focus seems to be directed towards further fortifying their fortress, shaping it more into an entire city, while also working on his own "pet project."

While Cadmus is currently well absorbed into his tyrant persona, he isn't the sort to lash out at others or be particularly cruel towards his allies. For the most part, he conducts himself in a cold, refined matter, something like a "true professional" king. He is also open to discussing his former kingdom and its curse, seeing parallels between Thebes and the Yggdmillennia, and seeing that hubris may result in their downfall.

The only thing that isn't open to discussion is his nature as a dragon. Even stories of the Ismenian Dragon are kept vague, portrayed more as a lesson rather than a boastful legend. Any suggestions of Cadmus progressing his second Noble Phantasm further are met with deflection, mainly of Cadmus stating that [url=https://youtu.be/SSKXAavTLQI?t=445]he is already a dragon.[/url] Further pressing of the issue would likely lead to hostility. pls dont poke the dragon

I'll throw up what Cadmus's prep is looking like once I know who his Master is and we have all the Masters confirmed, just so he could plan his preparations around them accordingly.
