Habd was a retired Redguard sailor.
Habd bought Frostflow Lighthouse to live with his wife, Ramati, and his children, Mani and Sudi. Several days after they moved in, noises began coming from the cellar, so he went to the nearest town to buy some traps for what he assumed to be Skeever. Returning, he found Ramati's corpse and a Chaurus, which he killed.
Desperate, he hoped to rescue his children, locking himself in the cellar so that the remaining Chaurus could not get past him to the surface again, but was captured by the Falmer, who had built a den for themselves and their Chaurus in the abyss below the cellar. By this time Mani had been killed and Sudi had also been captured. His rescue attempt was a failure, and he contracted a fever through Chaurus poison. Delirious, he left an iron dagger to Sudi when he was taken away, which she later used to kill herself.
The Dragonborn will be unable to save anyone of the family. However, picking up a clue before entering the cellar, they can at least fulfill Habd's final request.
The Dragonborn may find his decomposed remains inside a Chaurus Reaper and throw them to the fire at the top of the beacon, so that Habd can be able to look over the sea. This grants the Dragonborn the Sailor's Repose active effect.
