Red Sonja, Vol. 4 #15C

In the penultimate chapter of "Hell or Hyrkania", Sonja  returns to where her adventure started, the nation of Meru, to find it completely under the iron rule of Kulan Gath - who is using the native magic to grow more powerful than ever. The wizard needs to be stopped once and for all, before he finally gains the omnipotence he craves... but there's one thing standing between Gath and Sonja - and it's something the she-devil never expected to face.
