Message
Aboard the Covenant Supercarrier Sublime Transcendence, the Unggoy Kwassass opened a message from Vice Admiral Danforth Whitcomb that gave a full description of the weapon:

"This is the prototype Nova Bomb, nine fusion warheads encased in lithium triteride armor. When detonated, it compresses its fusionable material to neutron-star density, boosting the thermonuclear yield a hundredfold. I am Vice Admiral Danforth Whitcomb, temporarily in command of of the UNSC military base Reach. To the Covenant uglies that might be listening, you have a few seconds to pray to your dammed heathen gods. You all have a nice day in hell."
