[SPOILER!] - Concept Artwork: the Slayer (Patreon)

"What would you do if goblins took away everything you ever had? Everyone you ever loved?

What would you do if they burnt down your home, slaughtered your father and brothers like pigs, and then raped your mother and sisters as they kicked and screamed, then when they were broken and moved no more, dragged them away to their pits...?

... Would you be able to forgive? To forget what they had done? ...  I don't think so."

The Slayer is a grim member of the Mercenary faction, who becomes Claire's ally as the questline progresses and Claire finds herself dealing with goblins, a race of diminutive monsters, individually no stronger than a human child. However, when in groups, goblins become possessed of a deadly pack-like cunning, and can take down even seasoned warriors.

In the wake of Zeon's war to wrest total control of Rathpike, many outlying settlements were left bereft of protection as the able-bodied men were pressed into service. These hapless settlements became privy to the goblin raids. They attacked these places that were guarded by little more than old men and untrained boys, then raped and pillaged with impunity.

One such village was the home of the person that would grow to become the Slayer.  After losing everything, the Slayer burned with a vengeful thirst that could not be slaked with anything short of rivers of goblin blood.

Now, in the Narfu Outpost commanded by Belisaros, the Slayer is one of his most trusted soldiers. Known to venture out for weeks on end, presumed dead by all, only to return with a sack of severed goblin heads, the Slayer has near-singlehandedly kept the frontier at Narfu goblin-free.

While somewhat derided by other mercenaries for choosing to target what they perceive as a weak, child-like foe  (after all, what is a goblin compared to a manticore, or a rockbeast?), the Slayer's deadly work ethic means nobody dares to voice their insults as more than a muttered comment. And even then, never in the Slayer's presence.
