Daer Krand is a dark wizard and a former student of Zandar Horfyre. He can be found upstairs in the eastern wing of the Sisterhood Sanctuary, just north of the the Nightmare's arena.
Daer Krand came to the Sanctuary to research the Elixir of Everlasting, a legendary potion that is said to extend the drinker's life indefinitely. However, being more adept in magic than Herblore, he has a difficult time trying to recreate the potion.
Daer Krand is the solution to the hard anagram clue: DARN DRAKE. He will give the player a puzzle box.
