All underground locations created by legions and other forces, i.e. tunnels
and trenches and the like, have been eradicated. Their contents will have
ended up on the appropriate surface location.
YOU ARE NOW ALL READY TO GO: to dig and tunnel and network your way
through the continent.
The wipe been done to give a clean slate to everyone now the underdeeps
system is in place, as part of warfare (and integrated into various other
skills) - so tunnels, trenches, underground caves, lakes, floodwaters,
other curiosities: all awaits. I've no doubt that underground strategies
will become an important component of warfare. Mark my words!
