Hi lazylob,
I don't know about a formal guide, but here's a quick overview of what to expect.
The zone is divided into three major sections, the zone splits off into these sections from the hub just after Arreken Skyward:
East ToV
West ToV
North ToV
East ToV: East ToV is populated with trash mobs that drop the Glowing Drake Orbs (part of the ToV armor quest), the nameds drop 2 Symbols (e.g. Ruby Symbol, Silver Symbol etc et al). The nameds in East ToV are the least powerful and easiest to kill.
West ToV: West ToV has 3 named dragons, Gozzrem, Telkorenar and Lendiniara the Keeper - the last being the one who drops the
key to North ToV (Passkey of Many Treasures, neck item). These dragons are more challenging than the ones in East ToV, but not as difficult as the North ToV dragons. The trash in West ToV has a change to drop Ancient Tarnished armor pieces, which you hand in with 1 Glowing Drake Orb and 2 Symbols for the ToV armor quests -
Jeido posted a great guide describing which symbols are used for each piece, you can find it
here. The other named dragons drop different pieces of jewelry and weapons.
North ToV: By far, the most challenging of the three wings. Only one person needs the key from West ToV to open the door to North ToV. Many of the named dragons (and even some of the trash) are hasted, and seemed to be immune or highly resistant to slow*. Many of the nameds in North ToV count toward the Epic 2.0 quest, and given the increased difficulty, it's recommended that you spend some time in East and West ToV and get your party geared up before you attempt the North wing.
I know this isn't much of a guide, but I hope it helps give you an idea of what drops from where and how you might progress through it! Good Luck!
