You're right (Destiny)

It's also not an ability unique to the Hive. Hiding your "death" somewhere safe so you can be resurrected seems very similar to the function our ghost serves.

I was trying to figure out how the Ghost mechanism is different than how the Hive do it, but I haven't come across something solid yet. They're similar, but seem to have fundamental differences in that the Hive variant requires a different dimension, whereas the Ghost method requires the Ghost/Light.

For the Hive, a True Death means to die in your throne world. For Guardians, a True Death means that your Light/Ghost is lost.
