Story: Lich is a ghost being created by Mallory out of armor and made to be solid, as was Vie (a weaker ghost being made by Mallory who Lich looks up to and sees as an older bro). Lich was made specifically to go adventuring, so they do so a lot; they are helpful and kind by nature, despite being made to be a sharp weapon.

Personality: They are confident in the realms of fights, but they are pretty awkward in other (nonphysical) areas, and pretty gullible (especially if you say the key words "it's what a hero would do").

Attributes:
Club tail: Lich's main attack.
Silver spines: The spines on their hands and chest can shoot out, or even be plucked out and thrown to be aimed. Normally they are protected by soft tertiary fur, but when tensed, the spines spring out.
Metabolism: Due to being a ghost made solid, Lich has an extremely fast metabolism, and needs to eat lots to maintain form.
No fullness/hunger: Being a ghost, Lich doesn't really have the same senses of fullness or hunger (unless altered to have such).
Digestion: Lich can basically digest anything.
Intangibility: Lich can only go intangible when extremely weakened, and in doing so they drop their armor (except their head). They cannot go back to tangibility unless they are recharged; it's a weakened state (obviously not good for battle) but it's good for fleeing (discretion is the better part of valor).
Regeneration: Lich cannot be killed; they can be destroyed, or parts of them removed/destroyed, but they will always come back, and the parts will grow (if destroyed) or reappear on them (if not). A full destruction means they will come back in ~ a week.
