Rulah Jungle Goddess #21

Rulah battles a jungle witch named Gahna who has placed a curse on her lover, causing him to transform into fire with "the red death." When Amazo, another jungle inhabitant, accidentally wounds Gahna with a poisoned arrow, Gahna mysteriously sinks into the ground. Rulah then encounters a civilized metropolis hidden deep in the Congo, built by enslaved peoples, where she is warned that her presence is known and poses a great risk to those she cares about.
