His name was Kabr. He wasn't my friend but I knew and respected him as a Guardian and a good man.
He fought the Vex alone. This destroyed him. In the time before he vanished he said things that I think should be remembered. These are some of them:
"In the Vault time frays and a needle moves through it. The needle is the will of Atheon. I do not know the name of the shape that comes after the needle.
No one can open the Vault alone. I opened the Vault. There was no one with me but I was not alone.
You will meet the Templar in a place that is a time before or after stars. The stars will move around you and mark you and sing to you. They will decide if you are real.
I drank of them. It tasted like the sea."
That is all I can remember.
