Merlin's Apprentice (sometimes called Merlin's Apprentice: The Search for the Holy Grail) is a 2006 miniseries. Though also produced for Hallmark, it is not a sequel to the hit television miniseries Merlin from (1998), but does feature Sam Neill as an alternate version of Merlin and Miranda Richardson returning as a very different Lady of the Lake.
While being vaguely based on Arthurian legend, its plot is set after the death of King Arthur and completely different from the traditional legends.
Satisfied at Camelot's conditions, Merlin decides to go on vacation in order to rejuvenate. This vacation nap is supposed to last a few months, but when Merlin awakes, he finds he has slept for fifty years. Upon his return to Camelot, he discovers a downtrodden place. Almost all of those he knew have died; Lord Weston runs the kingdom; and the Holy Grail has departed from the castle. However, Merlin's protective enchantments have held invaders in check.
