In 860 BCE, Kucknoi participated in the skirmish at the Planet of Blue and Red, during the San'Shyuum-Sangheili War. During the battle, he was the head researcher of Site One on the planet, charged with excavating and documenting a Forerunner structure at the site. At the orders of High Lord Mken 'Scre'ah'ben, Kucknoi and the rest of the researching team retreated from Site One and returned to the Forerunner Dreadnought orbiting the planet. As he returned to the keyship in a shuttle, Mken contacted Kucknoi, the latter being surprised that the High Lord had given orders for the Dreadnought to fire upon the Forerunner structure. Mken assured him that the keyship's weaponry would not harm the structure, only kill the Sangheili troops at the site. Kucknoi reported his discovery of air shafts that led to a subterranean chamber within the structure, but that his research team was unable to explore them before they were given the order to retreat.
