It is unclear whether Gygax initially intended the two names to refer to the same character.

"Gygax provided no further context for who Tasha was, but an adventure published in Dragon #83 (about two years after Tasha's Hideous Laughter first appeared in the pages of that magazine) mentioned a 'Natasha the Dark' in an adventure exploring Baba Yaga's hut". In 1984, Dragon #82's article on magical research added the spell book "Lore of Subtle Communication by Tasha" which included the following spells: ventriloquism, message, comprehend languages, legend lore, and Tasha's uncontrollable hideous laughter. The spell, Tasha's Uncontrollable Hideous Laughter, was then included in a list of magic-user spells in Dragon #67.

The name "Tasha" and the association with laughter were created when a young girl sent Gary Gygax a letter (in crayon) asking him to create a spell involving laughter. This adventure also introduced the Demonomicon of Iggwilv which was described as "a treatise on the powerful evil creatures of the lower planes". Iggwilv debuted in Gygax's The Lost Caverns of Tsojcanth (1982), "an adventure where players explored caverns once occupied by the powerful arch-mage". The name of Louhi, a character in the Kalevala, is given by Gary Gygax as an alias of Iggwilv. Gygax has cited the Finnish epic Kalevala as inspiration for Iggwilv.
