I he'd canon this is the night before the sealing and the pale king is currently saying goodbye and why he is doing this
First time I drew the pale king that's why the horns look silly I head canon the pale king knew about the true ending (the radiance is killed by the knight) and he sacrificed his kids, kingdom and everything else to save the world the radiance, and yet he knows about pharloom through herrah, his foresight (looking at hornets mission into pharloom) and merchants.
