all the weapons ever created. As per Bhishma, the constellation under which the sword was born is called Krittika, Agni is its deity, Rohini is its gotra, Rudra is its high preceptor, and whoever holds this weapon obtains victory for sure. Nakula received this sword from Guru Drona. Drona received Brahmashira from Guru Agnivesha and he was also the student of Sage Bharadwaja. Role in the Kurukshetra War Dronacharya had been the preceptor of most kings involved in the Kurukshetra War on both sides. Dronacharya strongly condemned Duryodhana exiling the Pandavas, as well as the Kauravas' general abuse towards the Pandavas. But being a servant of Hastinapura, Dronacharya was duty-bound to fight for the Kauravas, and thus against his favorite Pandavas. After the fall of Bhishma on the 10th day, he became the Chief Commander of the Kaurava army on the 11th day of war.
