Nagrom was a male Kinshaya and leader of a faction of Devotionalists. Where the Devotionalists and their leader Yeffir sought to remove the ruling regime via non-violent methods, Nagrom was willing to utilize a more aggressive approach.
In 2382, he was noted to be "burly" and his fur was scarlet colored. When a group of Romulans, members of the Unification movement, met with the Devotionalists in Rashtag on Janalwa, their attitude of non-violence helped bolster Yeffir's position within the organization, and sway over Nagrom's faction.
At their first public rally, Yeffir addressed the assembled crowd; as Inquisitors moved in to disrupt and scatter the protest, Yeffir urged no retaliation, but Nagrom and his more aggressive compatriots faced off with the aggressors. With the escalation, Breen forces utilized disruptor pistols to bring order, causing several Devotionalists to be killed with many more injured. After the Devotionalists retreated and regrouped, Nagrom branded the Breen as demons, and urged the uprising members to rally the people to fight back and drive out the Breen and Episcopate.
A second rally held the next day drew a much larger crowd, and a violent response from the Breen troops. The Devotionalists - even Nagrom - stood firm in the face of the disruptor fire as hundreds died around them in an event that would become to be known as the Niamlar Massacre.
