Some of the things I’ve happened upon.
Nazjatar: 1. stone shelf overlooking Bloodfin Village: a ship with a human skeleton next to a barrel, which is next to the shrine of Izaka with two Ankoan skeletons and a bed…and there are also three stones with Drust runes on them.
2. shelf above Deepsea Slave Pens in Zanj’ir Wash, there is a ship broken in half (this can be seen from Newhome and Mezzamere). In between the halves is a Sea Spireshell addressing six Muck Creepers.
3. underneath road out of Mezzamere, on top of the waterfall draining into Dragon’s Teeth Basin, is a cave with a shrine to He-who-shall-not-be-named and four Ankoan skeletons. There are six baskets and one has a cat figurine in it. Technically one doesn’t need to fly to get there, but it is hard to see where to jump onto the ledge.
4. In the shelf above Newhome is a hole where the sea giant Gormson sits, if you want to keep him company. Also flying is not essential, but makes getting there not-fatal.
5. above shelf over Brinestone Cove, overlooking Chitterspine Caverns, look out to the ocean, through the magical barrier, where waits the great sea beast Charybon…
6. Above the shelf overlooking Azshara’s Palace and the Abyssal Pool are 20 sandclaw scuttlers along a ledge dancing in unison.
7. Above a shelf on top of the Chamber of the Harvesters, overlooking the Deepcoil Tunnels, there is an overhang with giant coral on it, and another 20 sandclaw scuttlers dancing in unison. Which group is better? Hard to tell.
8. Over Mezzamere is a mountain. On the top, where one cannot fly any higher, is an easel and paint kit next to a table and horde shield. 9. On the Horde’s side of Tide’s Fall, one can enter the hull of the ship in the waterfall, which is filled with Spireshell Snails and Sandclaw Crabs eating Orc corpses.
10. On shelf above Deepcoil Tunnels overlooking Zin’Azshari, on top of a giant coral, is a Sea Spireshell being attacked by 9 sandclaw scuttlers-some even continue attacking when dead!
Zuldazar: Mount Mugamba: on highest peak south of Atal’dazar is a dragon skeleton with giant spears sticking out of it. Below this, overlooking Gorilla Gorge, is a lake filled with Shimmerfin and jungle gulpers. There’s also a cave with a broken Zandalari pot in it. A Night Elf was fishing there (a player, not npc) when I found it.
Tiragarde Sound: 1. in southern mountain range next to Drustvar, on highest peak overlooking ocean, is a Kul Tiran shack and a Racing Pengling. Clicking on it will send the you down a blue streak of ice being chased by a yeti to a finish line and a Kul Tiran barker.
2. on highest peak overlooking the Waning Glacier, is the skeleton of a storm dragon from Stormheim with a chain coming out of it’s mouth next to an orc skeleton (I’m assuming Dragonmaw) and a shattered boat with a Proudmoore flag. (Someone had a bad day.)
Drustvar: 1. on highest mountain south of Gol Koval, pointing towards a mountain in Tiragarde Sound, is Iwen’s Sanctum (the name appears on the screen). It’s yer stereotypical Drust cave.
2. Mount Cortis, the highest mountain in the zone (roughly center), on the peak, is a humanoid skeleton holding glaives next to gold pentagonal things, above it is a sign saying “First” defaced by claw marks.
3. Baby Wren (so named at Blizzcon, spelling guessed at). In the Crimson Forest, in the large tree next to Sister Martha’s house, is a human/gnome baby in a nest being tended by a long-billed blue-headed bird. The baby blinks and stretches its neck.
And that’s all I’ve seen so far.
