Future
Khan's current political value didn't come from his strength. While that had worked in the past with minor families and soldiers, the nobles required something else. Those immense organizations simply didn't care about his battle prowess.
Owning something no one else had was the only way to gain value in those environments. Khan's supplement, magic item, and unique relationship with the Thilku were his best weapons and shields against the nobles, especially the latter, since it was connected to his figure. That advantage would disappear without him, making his figure necessary.
Amassing other advantages with a similar nature was Khan's best strategy in a world filled with political powerhouses. The more necessary his figure became, the safer he would be. His influence would also grow accordingly, earning him true power over otherwise untouchable environments.
