Lif ("Birdpipes")
An invisible, incorporeal being that dwells in Trollskull Manor and really wants it to be reopened for some reason.
Specter
Usually, Lif is invisible, inaudible, and intangible. When made visible by magic, he appears as a humanoid figure with indistinct features, partly obscured by roiling smoke. To those who can hear him, his voice sounds quiet and raspy with a pr0n0unced h0ll0wness.

Long and wispy, floats in the air around him like gentle ripples of smoke
Spooky
I guess he's technically naked, huh?
Generally peaceful unless provoked, and his acts of violence are more like those of a tantruming child than a vengeful specter - slowly piling trash on top of the offender, or pushing them down a couple of stairs, for instance. He doesn't lash out at those who don't provoke him, even when he's already angry.
He wants to be friends with those who share his home, and has repeatedly expressed a desire to help.
Fixated on the state of Trollskull Manor, and in particular wants the taproom to be reopened. He gets upset and lashes out when harm is threatened against himself or the building.
Semi-corporeal - can interact with material objects or living beings when he wants to, but so far hasn't allowed others to touch him.
He instantly took a disliking to Edward the Magister, recognizing him as a "murderer" of ghosts.
