This outraged his elder half-sister Pendiongmu (daughter of the first wife of Tensung Namgyal), of Bhutanese descent, who opposed the succession and with help from Bhutan evicted Chador.

Chador fled to Tibet (Yungthing Yeshe, a loyal Minister escorted the minor king to Lhasa) where he remained in exile for ten years before returning and reclaiming his lost territory with the help of the Tibetans.

During his exile, the Sixth Dalai Lama pleased with the erudition of Chador Namgyal had conferred on his exclusive rights to an estate in Tibet.

With the help of a medicinal man from Tibet, she got Chador Namgyal murdered in 1716 through mysterious bloodletting from the main artery while the king was on a holiday at the Ralang hot water spring.

Immediately, the royal armed forces executed the Tibetan doctor and also put Pedi to death by strangling her with a silk scarf.

Since he did not have any legitimate children, on his death bed he conveyed that a nun at Sanga Cheoling was carrying his child (this is said to be the story concocted by the Lamas to perpetuate the Namgyal dynasty).

Subsequently, the nun gave birth to a male child who was accepted as heir to Gurmed and was given the name Phuntsog, after the first temporal and the spiritual head of Sikkim.

Bhutan had also attacked Sikkim and occupied areas east of Tista River; however, they later withdrew to present frontiers after negotiations held at Rhenock.

Consequent to the repeated attacks by the Bhutanese and Nepalese over the many invasions, the capital city was reduced to ruins by the liberating army of Nepal.

This wing has an open quadrangle where the "Dab Lhagang", now in ruins, is also seen; the royal family used to offer prayers with incense to their deities here.

The Archaeological Survey of India has declared Rabdentse as a heritage monument and has undertaken the needed preservation and restoration measures.
