anything like this maybe?
.
Sorry for that.
.
Seriously, I checked in the official french Eberron rulebook D&D3 version)
The Coin Lords are known as "L'Aurum"
The Silver Flame is "L'Eglise de la Flamme d'Argent"
The Twelve are... well, "Les Douze"
Other background notes:
The Sovereign Host is "L'Ost Souverain"
The Undying Court is "La Cour d'OutreMort".
More to come, if needed.
BTW , though I can understand why quest should not be translated... if they had to be translated, then most of them should be renamed. When it happens that the translation make sense, it often loose the particular flavor of the original version. Too bad.
