Quest completed

You find Guards and Defenders at the massive High Elves gate between Shadowlands and Ellyrion. But you have to look closely to find 2 Guards (or Defenders can't recall which it was) but both NPC types are there, afterwards you move through the gate into the next zone to the next quest-hub where you continue with your epic quest in Ellyrion.

Ok, quest description completed, hope it would be updated on the WIKI

Thanks.

Thanks for updating (some formatting would be nice too)

I have no idea where to post it, but this quest is stupidly hard.
Is this the only T2 epic quest, that requires a second stage of the hard PQ (at Step 19)?
To do that you need to kill 100 monsters. When you are coming there, it's usually 10-20 from 100 needed, so all of this kills would be on you only - this is unwilling exp.
Then, you have only a small time-gap to kill 3 champions of the 20 lvl, that is nearly impossible task for classes without self heal (like SH) at lvl 18-20. Before I did it at Mara, it wasn't too hard.
At SH this is crazy impossible, cos monster absolutely ignoring my tank-squig, and attacking me for ~500 damage per shot (I have only 3k HP there).
Probably, Ellyrian Commanders must be changed to Ellyrian Defenders - there is a lot at 1st stage of PQ and this is usual monsters.

Where are the Elders for this quest? I can only find Elder Meresene.
