Einar

Einar is the protagonist of side story 2.

Born an orphan and raised by monks, Einar had a simple but fulfilling life until it was all upturned by a wrathful lingering spirit tearing through the city where his monastery was. The spirit ended up inside him and, after receiving immortality from the god of death, is trapped inside him forever. Einar now dwells within a remote valley to prevent the spirit from ever harming anyone else again.

Powers
Einar was raised a monk, and has had thousands of years to master ki. Aside from the usual benefits this would grant - namely enhanced senses - He has reinforced all of his vital organs to be tougher than mithril while his limbs are nowhere near as tough, so the possessing spirit has no means of killing him and escaping to another person.

Immortality - Does not age, and will live forever barring some extraordinary disease or attack able to get past his resistances.

Healing techniques - Before the monastery was destroyed, Einar specialised in healing techniques, and developed them beyond what was formerly considered the limit, allowing him to heal not only other people, but also animals and plant life.

Wrathful spirit possession - Under the force of the spirit inside him, Einar is forced into being a spectator in his own body as the spirit takes over. Murderous and sadistic, the spirit is a veteran of many battles and fights with great skill and instinct. They also fight with little regard for their own safety, and will unhesitatingly sacrifice limbs if it will help them acquire a new body.
