For non-special servers, I think Ayonae Ro (sp?) is the newest - it is a
split server. The newest US server started from scratch is indeed Vazaelle.
But it's about 18 months old.
Including special servers, I think the most recent in order are Stormhammer,
Firiona Vie, and Sullon Zek.
Thinking about it further, Zebuxoruk may be a newer split server.
I believe Tholuxe Paells is the youngest non-split server, about 17 or 18
months old now. maybe a tad less.
