The sisters were Parameswari Tribhuwana also known as Trubhuwaneswari (the eldest), Prajnaparamita, Narendraduhita, and Rajapatni Gayatri (the youngest).
The reason for Dyah Wijaya's practice of sibling polygamy was to ensure his claim of legitimacy and to prevent the contest for Kertanegara's Singhasari legacy.
Dyah Wijaya also married Indreswari (also known as Dara Petak), the princess of the Malayu Dharmasraya Kingdom, who was brought to the Majapahit court from Sumatra through Kertanegara's Pamalayu expedition.
[2]: 454 Dyah Wijaya or Prince Nararya Sangramawijaya ascended to the Majapahit throne and took the regnal name of King Kertarajasa Jayawardhana in circa 1293/1294.
Sukamerta and Balawi inscriptions mention that from parameswari (primary queen) Tribhuwana, King Kertarajasa begot a son named Jayanagara.
To reconcile these accounts, some historians have suggested that Jayanegara was Dara Petak's biological son but was adopted by the childless Queen Tribhuwaneswari and raised as her own.
With the help of Gajah Mada and his palace guard,[1]: 233 Jayanegara barely escaped from the capital and safely hid in Badander village.
For his loyalty and excellent service, Gajah Mada was promoted to higher office and began his career in court royal politics.
However, she became a bhikkhuni and was therefore prohibited from holding positions of political authority, so her daughter, Tribhuvana (Tribhuwana Wijayatunggadewi, or Tribhuwannottungadewi Jayawishnuwardhani), became regent instead.
The gate was identified as part of Çrenggapura (Çri Ranggapura), his pedharmaan, the Kapopongan of Antawulan, a holy compound to appease and honor the soul of the late King Jayanegara.
