Glen Baskerville (グレン バスカヴィル, Guren Basukaviru)
Glen Baskerville is the antagonist of the series and was
Jack Vessalius' best friend and also
the leader of the Baskervilles.
Glen was also known to be friends with Arthur Barma
(the man who bound Glen's soul)
and Raymond Nightray.
Glen also has an unknown relation to a woman named Celia,
a Baskerville who told Jack about Humpty Dumpty and Glen.

Glen Baskerville is not entirely human,
more comparable to a Chain, as are the rest of the Baskervilles.
Glen though has to possess bodies
in order to sustain life and with
each movement Glen creat Chains
through his discarded bodies.
He created Humpty Dumpty and it is
assumed that that is also how he obtained
The Black Feathered Chains of Glen Baskerville, the
Jabberwock, Dodo, Owl, Raven and Gryphon.
This transfer lets Glen keep his memories while the
vessel's personality is retained.

"Whether they are a woman or a child...
kill every single person in this town!"
