Government drone by day and book lover and geek girl by night!
"The palace of yakshas and yakshinis."
Finally looked up these words since the book has mentioned them. Here is a visual for you all:
Yaksha (Sanskrit यक्ष yakṣa, Odia-ଯକ୍ଷ, Pali yakkha)[1] is the name of a broad class of nature-spirits, usually benevolent, who are caretakers of the natural treasures hidden in the earth and tree roots.[2] They appear in Hindu, Jain and Buddhist texts.[2] The feminine form of the word is yakṣī[3] or Yakshini (yakṣiṇī).[4]
