Death is part of a Cloud Strider's lot. Nimbus knows this, but that doesn't make Rohan's early exit any easier to accept.
Still, he made every moment count; by destroying the Radial Mast, Rohan wrecked the Witness's plan for creating a link with the Veil.
But that doesn't mean the war is over. Calus is sure to retaliate—and it looks like his sights are set on the CloudArk.
There's no time to mourn now. The best way to honor Rohan is to get Neomuna's defense systems up and running again.
You might check in with Osiris and Caiatl in the Hall of Heroes before jumping back into the fray.
Complete the strike "HyperNet Current" in Neomuna.
