Ramona is a Wild Elf Mandrake Druid, who used to live with her people in Pendegalas.
Somehow she came upon the knowledge of finding and controlling the enigmatic creatures that make up the Swarm. She started expanding her control over animals and plants in Pendegalas, reaching some of the wild elf tribes settlements. The wild elves tried to defeat her but the Swarm was so strong that she managed to get all the tribes to leave Pendegalas as fast as they could, even leaving their dead behind.
The Swarm was seen in the battle against the phaerims fighting along the armies of Necropolitans, Gnomes, Hobgoblins as well as the Yoentumak Company and the Wererats.
