Who persuaded ressendyll to impersonate as the king of ruritania and why?

Rassendyll was persuaded to impersonate the king of Ruritania by Duke Michael, the king's illegitimate uncle, who sought to usurp the throne. Michael believed that Rassendyll's striking resemblance to King Rudolf V would allow him to manipulate events to his advantage. The plan aimed to secure Michael's control over the kingdom while Rassendyll, initially reluctant, was drawn into the intrigue due to a sense of duty and adventure. Ultimately, Rassendyll's decision was influenced by a desire to protect the rightful king and the stability of Ruritania.
