From Destinypedia, the Destiny wiki
During the fall of the Last City to the Cabal's Red Legion, Daimos-22 escorted groups of civilians to safety. While evacuating an underground compound that was flooding he brought the civilians living there to the last remaining tunnel that led to the surface and encouraged them all to move quickly. The tunnel was collapsing, so Daimos positioned himself under the weakest point and held up the support structure as the refugees streamed past him, and when one woman dropped a large suitcase she was struggling with he quickly kicked it out of the way and had her keep moving. As the structure began to collapse more, Daimos resolved to hold on as long as he could while the civilians escaped, and he did not let go until the last civilian escaped, although it cost him his life as the tunnel finally collapsed completely and flooded.
