Veilwater River

Shadow Realms — At the start of your hero
phase, you can pick one friendly unit that has all
of its models within 6" of any edge of the battlefield. Remove that unit from the battlefield,
and then set it up more than 9" from any enemy units, and with all models within 6" of a different
edge of the battlefield. Then roll a dice for each
model you moved; on a 1 the model being rolled
for is slain. The unit may not move in the
subsequent movement phase.
