Sump Sea

Zone Mortalis — discard this Environment and
draw another. When setting up the battlefield,
try to set up as many walkways and raised
sections as possible, and allow for a path from
one side of the battlefield to the other.
The ground level is a Sump Sea and fighters
must remain pieces of terrain. If a fighter falls
into the Sump Sea, place them where they have
fallen — falling into the Sump Sea doesn't cause
any damage.
