Calamitas Doppelganger: After her return to Yharim's side, Calamitas was transformed into a gigantic eyeball by the tyrant as a reminder of what would happen if she should betray him again. Eager to be of assistance, Calamitas was the the first of Yharim's lieutenants to volunteer when the tyrant asked for an assistant for his next project. When Calamitas volunteered, Yharim took took her to his laboratory and took a sample of her DNA. Yharim then infused rock shells with the DNA and calamitous material for the DNA to breed in, creating an army of Calamitas clones.
Aquatic Scourge: A gigantic worm, distantly related to the eidion wyrms, and of the same genus as the desert scourge. It lives in one of the seas near Amidias' sea, and narrowly avoided having its domain dried up by Calamitas. However, the brimstone fallout from Calamitas' rage against the neighboring sea hit the sea, dissolving and imbuing the sea with toxic sulfur.
Ravager: Yharim's mother had always been friendly with the lizhards of the lizhard temple. However, after her death, her tyrant son, after his near escape from death in the underworld lava like the rest of his family, with the assistance of Yharon, purged the leaders of the jungle, including the lizhard king. Yharim then set up his base of operations in the jungle temple, enslaving and cursing the lizhards. Later, after the disastrous failed experiment resulting in the bumblebirb, Yharim resolved to create a mechanical terror, more under his control, and possibly less likely to fail. He used the reinforced bricks of the jungle temple, as well as cosmilite to create heavy armour for his planned creation. Then a thought struck him. Gathering the corpses of lizhards that had been overworked to death, he fused the armour with their flesh. He then ordered Calamitas to give the abomination a basic mind of destruction. Thus the ravager was born.
