Mayasura

Maya or Mayāsura, also called Maya Danava, is a figure in Hindu history, described as the king of the Danavas, a race of beings descending from Kashyapa and his wife Danu. He is known for his architectural expertise, credited with creating the Mayasabha for the Pandavas and Tripura for the sons of Tarakasura. In the Ramayana, he is mentioned as the father-in-law of Ravana. He is presented as an architect of Maya. In the Surya Siddhanta 1.02, Mayāsura is described as a Daitya who received divine astronomical knowledge from the Sun God sometime around the end of Satya Yuga.

In the ''Mahabharata''

Mayasura is mentioned to be a son of the sage Kashyapa and his wife Danu.
Mayasura had befriended a Nāga named Takshaka and lived with him in the area of Khandavaprastha along with his family and friends, but when the Pandavas came there after the partition of Hastinapura, Arjuna burnt the entire forest, forcing Takshaka to flee and killing everyone else. This made Mayasura decide to surrender to the Pandavas. Krishna was ready to forgive him and in return, Mayasura built a grand palace named Mayasabha, where the Pandavas would perform the Rajasuya Yagna.
Mayasura also offers him gifts like a bow, a sword etc. He gives a mace to Arjuna's brother Bhima named Vrkodara. In some versions of the Mahabharata he also gives Arjuna the Gandiva bow.

In the ''Ramayana''

The Uttara Kanda of the epic Ramayana mentions that during his visit to Svarga, Maya married an apsara named Hema. They had two sons — Mayavi and Dundubhi — and a daughter Mandodari, who later married Ravana, the Rakshasa ruler of Lanka and the main antagonist of the epic. In some versions of the Ramayana, Maya had another daughter named Dhanyamalini, who also married Ravana.

In some folktales from Bengal, Mayasura is married to Oladevi, the goddess of cholera.
