Dune
Can forces battle when the storm covers part of their territory, including a stronghold?
The rulebook text is explicit; the designer favored a different house reading but made no ruling.
Not while either side is in a sector under the storm; they stay in place and fight when the storm has moved on. The rulebook makes no stronghold exception, and the designer said they would raise it and personally preferred allowing it. Shared occupation under the storm does not count toward victory.
