BellaOnline Forums Computers Computer - Console Gaming Help missing key items

with all my ranting about eigaar, I almost forgot what I intended to ask:
I seem to be missing 2 key items (other than the al bhed primers i didn't get):
the first one should be just abovethe "withered bouquet"
the second should be just below the "aeon's soul"
Could somebody let me knwo what's supposed to be in those blank spaces and where I am/was supposed to get them? I hate having blank spaces in my key items ;-) Thx.

The withered boquest is below the Cloudy mirror. If you powered it up to the Celestial mirror, it disappears and nothing replaces it.

THe other one is probably the Mark of Conquest, which you get for beating Nemesis. Good luck....

Nemesis? Hmmm... The name rings a bell, but I can't quite remember who or what and especially where he/she/it is? Could you maybe jog my memory on that?

oh, and does the mark of conquest do anything for you or can you just be happy about having gotten it/having beaten nemesis?
