Trying to find out a specific raid name

Hi there, I am looking the name of a specific raid. I did half of it once long ago and I'm not sure which one it was. I'm a fairly new player but at the time of doing the raid I was very new so I'm not exactly sure which it was.

In the raid, it was pretty green in terms of the grass and trees. You then went down a hill, and fought waves of mobs coming at you on this hill. After that you then moved up further along the hill and fought more waves of mobs and I'm sure there was a dragon involved somewhere or an npc flying a dragon. I'm not 100% sure but I feel like I remember there being a sort of little town or something as well at the top of the hill but I could be wrong.

The reason for why I'd like to find out what the name is, is that I recall there being drops for recipes, tailoring, and if I'm not mistaken there was a conjure refreshment rank 3 or something like that (for mage)

I hope someone is able to let me know the name, would be greatly appreciated :D

Have a wonderful day,

thank you <3

The raid you're thinking of is the Hyjal raid in the Caverns of Time.
