New Covenants (6th December, 2013)
New screenshots of Dark Souls II have revealed two new covenants. #The first is the Warriors of Sunlight, however, they can only be summoned by members of the Sunbro covenant.
 * 1) The other is called the Guardians of the Bells, and this will function in a similar manner to the Forest Hunter covenant in Dark Souls. However, the objective of this new covenant is to prevent trespassers ringing two bells hidden in the area.
