Lucas

History
The Striker Siblings were supposedly born at the same time as the underground was sealed by the Humans, although their true origins are still shrouded in mystery. They live together in a cave turned home above the lava lake in Hotlands.

They don't kill monsters but need either their blood or raw meat to survive, they train in the lava with their magic and they're specially made weapons during their spare time. They prefer to be alone with just each other for company, but willing to let others come over for occasional guests, they are good conversationists (at least Lucas). They are theorized to be very powerful beings, supposedly the outcomes of the Monster's hatred over humans. Wether this is true or not isn't certain yet.
