La Infestación

Origins

La Infestación (true name unknown) is an Erinyes from Baator, who served as a lieutenant and sometimes a concubine to an unnamed master. Irked by the fact that the misogynistic culture of the Nine Hells saw her passed over for advancement again and again, she conspired to charge her master for his derelict of duty, only for her supposed allies to betray her. Barely able to escape pursuit, the fiend wandered the wastelands of the Nine Hells in a state of mental turmoil and failed to notice the signs of Transposition on her own flesh until it was too late.

In the Dread Realms

The she-devil appeared in Vechor in the year 624 BC. The land's chaotic nature made her believe she was in the Abyss. She soon crossed over into Darkon, where she met the tanar'ri known as the Red Haunt. To her surprise, the other Fiend appeared to be uninterested in fighting, and was actually helpful in explaining a great deal about the Dread Realms, including fiendish Power Rituals.
