Ehren, formally known as Sir Ehren ex Cursori, is an incredibly intelligent Cursor in the service of Gaius Sextus and latter in the service of Gaius Octavian. Ehren was a close friend of Tavi and Max during their school years, and learned to use his single, weak fury to his advantage because weak furies are harder to detect than stronger ones. Ehren accomplishes several noticeable missions including freeing Varg from The Grey Tower, and his role in the Vord attack on Caulderon Valley. After the Vord war, Sir Ehren becomes Gaius Octavian's highest-ranking Cursor.
Ehren is not a particularly strong fury crafter, earning only a couple beads in his days in the Academy. He makes up for this with ingenuity, using what he can to great effect.
Ehren's woodcrafting is the only type he is able to use more than in a rudimentary sense.
