The Totem of Dera is the most magical and ancient of the Treasure of Thundera cache. It has amazing healing abilities so strong that they can even bring to life inanimate matter. These abilities were misused by the Mutants and Mumm-Ra to bring to life serpents made from the waters of the Baleful Swamp. At the end of a conflict with the ThunderCats, the Totem of Dera was lost in the struggle afterward in the toxic waters of the Baleful Swamp, from where it has yet to be recovered.
