Mare Cerulis
Founded: 1168
Status: Spring
Mare Cerulis (Deep blue-green sea) is a mobile covenant that consists of four ships of various size that operate in and around the Baelric Islands. They maintain a few sites (hideouts), and have a common lab on land (on Majorca, their only officially registered site).
They hold a grudge against Antonio because he killed one of their major assets when he killed the Balearic Dragon to earn his Archmagus status. He doesn’t know this, as Antonio has no idea who they are to begin with.
