Knights of the Blazing Sun -

# These classes are heavy tanks, but with a split. In some ways they have mechanics that act somewhat like the Swordmaster, in that they enhance their attacks through magic.
# The other major Chosen component is the Aura. Chosen can have can have up to three Dread auras active at a time, looping. The auras pulse out effects to surrounding players, some beneficial for allies, some detrimental for opponents. Some even do both; acting as a buff for you and debuff for everyone else.
# The Knight has shouted commands, which operate in much the same vein.
