Meanwhile, Parvata's brother Vairodhaka became the ruler of his kingdom. Chanakya convinced him that Rakshasa was responsible for killing his brother, and agreed to share half of Nanda's kingdom with him. Secretly, however, Chanakya hatched a plan to get Vairodhaka killed. He knew that the chief architect of Pataliputra was a Rakshasa loyalist. He asked this architect to build a triumphal arch for Chandragupta's procession to the royal palace. He arranged the procession to be held at midnight citing astrological reasons, but actually to ensure poor visibility. He then invited Vairodhaka to lead the procession on Chandragupta's elephant, and accompanied by Chandragupta's bodyguards. As expected, Rakshasa's loyalists arranged for the arch to fall on who they thought was Chandragupta. Vairodhaka was killed, and once again, the assassination was blamed on Rakshasa.
