Bring Samuel Fipps' Remains to Marla's Grave, then return to Novice Elreth.
My friend Marla Fipps lived with her husband Samuel before the plague, but when the plague came Samuel succumbed and joined the Scourge's ranks.
Marla was spared an undeath only to die at the hands of her now mindless husband. So strong was her love, however, that her last dying wish was to be buried with her beloved Samuel.
Samuel Fipps roams at a ruined camp along the road northeast of Deathknell. Defeat him and grant Marla's wish: bury him at her grave, in the first row of our graveyard.
