Conan the Barbarian #94 – “The Beast-King of Abombi” – Roy Thomas/John Buscema/Ernie Chan
This one starts with Conan and Bêlit saying goodbye to Zula, who has decided to forsake revenge in Kheshatta and head north instead. A handful of Bêlit’s corsairs are going with him, their desire for adventure on land stirred by the recent fights in Asgalun. Zula says his farewells and gives Conan and Bêlit one last reminder of his hypnotic abilities (by seeming to vanish) before leading his new friends inland. The Tigress puts out to sea and heads south to the Black Coast so Bêlit can get back to her life of piracy. But when they reach the village of the Matubis,
they find it burnt and empty. As they continue south, they find more villages destroyed, with no one left to pay the usual tributes to Bêlit. When they reach the village of the Watambi tribe (who they helped in issue 61) they find King Ombassa is a shadow of his former self, as are most of the villagers. Ombassa tells them that his daughter (Nyami) has been taken hostage by men who dwell in the ancient city of Abombi. Ombassa gives them the history of the dwellers of that city, led by an exile named Ajaga, who received from the gods the gift of being able to command animals. Ajaga and his men attacked villages to demand tribute, 
wiping out those who resisted. When Ombassa refused to pay (or hand over his daughter), Ajaga commanded his animals to attack the village and ended up carrying off Nyami. The tribe’s witch doctor tells them of Jhebbal Sag, a god of ancient times who was once worshipped by men and animals, when they still had a common language. But Jhebbal Sag’s worshippers fell away until only a few animals still respond to the ancient tongue, which Ajaga must’ve learned from the gods. Conan and Bêlit lead an expedition to Abombi to rescue Nyami and end Ajaga’s rule, since Bêlit has no wish to let him take all the goods from the local tribes instead of her. They approach Abombi from the rear, climbing up the sheer cliffs that they assume are unguarded. But some sentry baboons spot them and attack, commanded by Ajaga. Conan and a
baboon fall off the cliff into the forest below and Bêlit is captured by Ajaga, forcing her corsairs to surrender. This is a pretty good story, the first of a four-part tale about Abombi and its beast-king, Ajaga. Roy took the inspiration for this from a character in “The Scarlet Citadel”, a Robert E. Howard story about Conan that takes place decades later, when he’s king of Aquilonia. A jailer in that story mentions meeting Conan before, during the sack of Abombi, and claims to be the king’s brother. Roy took that small reference (which said nothing about Ajaga commanding animals) and expanded it into this mini-saga.
Conan the Barbarian #95 – “The Return of Amra” – Roy Thomas/John Buscema/Ernie Chan
This one follows the above issue, with Ajaga feeling triumphant over killing Conan and capturing Bêlit to add to his harem. Two brothers (Beeya and Krato) aren’t sure Conan is dead and want to go down to check, but Ajaga overrules them. Of course, Conan has survived, using the trees to slow his momentum and landing on the baboon to break his fall. He’s brough tback to consciousness by a curious lion and thinks he’s in trouble, until he recognizes the lion as Sholo, one-time familiar of Amra. Sholo
remembers Conan too and shows obeisance to him, since he’s the one who killed Sholo’s former master. Conan realizes Ajaga’s animal power must’ve drawn Sholo there, so he decides to follow the great cat to Abombi. Inside the city, Bêlit awakens to Ajaga’s taunts and is thrown into a dungeon with his other “brides”, although he’s decided he’d rather kill her than marry her. But he wants to exhibit her first to show off his power, which bothers Beeya and Krato, since they think killing her immediately makes more sense. They’re also worried about an old witch finder in the jungle (G’chambi), who has been 
talking crap about Ajaga to whomever will listen. In the jungle below, Conan and Sholo come upon a cave with a strange symbol scratched in the dirt outside. Sholo refuses to go anywhere near the symbol, so Conan heads into the cave and finds G’chambi (who apparently confuses Conan with the original Amra). G’chambi tells him the symbol represents Jhebbal Sag and that’s why Sholo won’t cross it. Conan asks if he can use the symbol to keep Ajaga’s creatures back, but before he can ask any more about it, G’chambi is attacked by a dinosaur that looks a bit like a velociraptor. Conan finds the prehistoric beast and kills it, but G’chambi is close to death from his wounds. Before dying, he teaches Conan to draw the symbol (which must be done in a precise way) and after burying the old man, Conan heads for Abombi again to confront Ajaga. This continues the Abombi story started
above, with more references from Howard’s original works. This time it’s from “Beyond the Black River”, where Conan tells someone he’s seen the sign of Jhebbal Sag drawn in the mud of a riverbank in Kush. He also says he saw it once before, scratched on the wall of a cave beyond the Vilayet Sea (a reference he also makes here). The story where Conan first saw the symbol has never been told as far as I know; Roy says he forgot about the reference and so never got around to telling that tale, and I don’t think any of the Conan pastiche writers did either. Maybe someone will get around to it someday.
