The writing on the Abyss Voucher becomes clearer.

It says 'To the heroes'

and that the Record Keeper for the Abyss Achievements, Alleph, should be found.
You, Player, have fought bravely for the Elyos.

I've been waiting for you.

You show how to be a shining hero.
A hero needs weapons that suit him.

Here, you will become a being that will shine among the Elyos in the Abyss.

You can buy Ring[pl:"Rings"] of the Guardian Troop Leader with the Abyss Points that I am giving you.

You can get it right behind me.

I wish this ring will make you even stronger.
