Well they're all fated to die one final time at the end of days for the Eldar Race (and possibly everyone else) the Rhana Dandra.
It is (IIRC) Mourgan Ra who brings them together for the final battle, and Furgan who dies the last. This is from the 3rd ed Codex.
The novel Path of the Warrior features Karandas fairly heavily towards the end (including someone actually experiencing putting on the armour).
One of the Inquisition War stories (now very very "old canon" incidentally) has the Howling Banshee Phoenix Lord attaching the Inquisitorial band in the webway, which implies that that's where they hangout in between battles.
(my spelling is atrocious, I know, and I'm writing this all from memory).
