Isayah

Isayah is a character, NPC, and merchant found in Fear & Hunger. He is also a hostile encounter if the player attacks him or goes on to complete the treasure maps he sold to the player.

Lore
A mysterious man, he is met during your adventures and walks within the dungeons. He seems to be a bit ominous due to his metal mask. Quiet and stoic, initially he ignores you. If you persist, he goes on to talk to you and eventually offers to sell you his wares. Of interest are the treasure maps that are used for within Ma'habre (optional side quest though one that is important and needed to be done for Cahara's S Ending).

Going by his left hand, he was affected by some sort of plague. Perhaps it was the one that was rampant in Rondon? It seems he has lost his right hand as a result. Perhaps he wears a metal mask because it might have also disfigured his face, along with other disfigurement on his body via the plague.

Loot
Drops his Iron Mask, which is useful as protection against Crow Mauler's Flock of Crow abilities as the mask will prevent it from blinding the one that wears the mask. Also it is possible to get Scroll of Fencing by using Pocket Steal.
