The first part was deciding what quest or zone. I decided I'd go for a quest, because there is not really a particular zone I like, though there are some I have fond memories of (for example, Netherwing dailies in Shadowmoon Valley).
In the end I managed to choose to pick one that has stuck to me for several reasons which I will explain below. The chain in question is the famed Cipher of Damnation questchain in Shadowmoon Valley, which also happens to be the start for the attunement process for Serpentshrine Cavern. Do not read this if you haven't done this questline, because it contains heavy spoilers.
The chain starts off when a member of the Earthern Ring redirects you to Earthmender Torlok in Shadowmoon Valley. Nature in this zone doesn't look too well (it's all dead and there's green lava and such) and you are sent on three quests to commune with the spirits. Anyway, having done that, you learn about a spell that may have caused the current look of Shadowmoon Valley, and you are sent to seek out Oronok Torn-heart, a scruffy looking orc hermit.
Oronok and his sons
Oronok puts you to the test by having you kill some things in the neighborhood of his place, and then he reveals you his story. He tells you:
"They [the words of the spell - red.] are know as the Cipher of Damnation: The words uttered by Gul'dan himself to shatter this land. The very spell that severed the last remaining tie the orcs had with the elements of Draenor."He then asks you to go search for his sons around Shadowmoon Valley. All three of them have some chores for you, and all three will eventually (after a quest or three each) give you a fragment of the cipher of damnation.
The grand finale
With the cipher recovered, you head back to Oronok and are asked to go summon an elite you have to kill with a group. The place of summoning is an altar in memory of Gul'dan, at the base of the volcano known as the Hand of Gul'dan. The spirit of Gul'dan can be found here, as well as some other shaman spirits. When you read the spell aloud (you may recognize it from the Black Temple trailer) your screen shakes heavily, and the lava in front of you starts to develop smoke.
In the smoke, Cyrukh the Firelord spawns, with one of my favorite game quotes I might add:
Little creature made of flesh, your wish has been granted. Death comes for you!And as you can see, he's one big, mean chunk of rock. I have very fond memories of this guy, because on my druid, I have tried every role on him. I originally did him as a balance druid. I have screens of this, and two of the randomly PuGed people would later end up in the same guild as me.
Later in my WoW career I would come back to help guildies and throw some heals, and even later I would be helping out by tanking him.
The reward is a nice blue item and a fire resistance necklace, but the special effects, including all sons and Oronok flying in to help out, and the effect of 'casting' the cipher, make this a very cool quest IMO.
Honorable mention: Dragonmaw Races
I should point out that I really liked the Dragonmaw races you can do for Netherwing rep. While I never beat Captain Skyshatter, I did defeat Mulverick and it was a fun and fresh concept. Learning the path he races and then trying to stay either ahead of him or right behind him made a very adrenaline-packed type of quest. Anyone remember that sharp dive on the north-eastern edge of the Netherwing Ledge ? He dives behind a ledge there and then 'pulls up' so you're right in his line of fire if you don't watch out.
As a sidenote I'd really appreciate some input on the layout. I got tired of the pitch-black feeling of the previous one, so I adjusted one of the basic blogger templates a bit so it matched my new header.
