The graveyard of the Nightsisters is meant to resemble the trees found in the forests. The actual structures are built from branches, bones, animal skins and shells.

In a reversal of what happens in Episode I, the battle droids look around as their opposing army -- the undead Nightsisters -- drop to the ground, no longer animated by a central controlling influence.

Longtime viewers of The Clone Wars will recognize the Defoliator tank, an experimental vehicle first seen in "Defenders of Peace," an episode from the first season.
