Horde quests

This quest doesn't seem to be part of a quest line any longer. The Saphires are crystals on the walls of the cave before you get to the instance.

Allegiance to the Old Gods
This quest line starts as a random drop from blackfathom (possibly only outside the instance, not sure) of a damp note. After returning the note you get a quest to kill someone inside the instance.

Amongst the Ruins
The fathom core is found underwater near the twilight ruins not far from Ol' Serrakis. Be prepared because when clicking it a boss will spawn. It seems to have a level 25 requirement as well.

Rewards: Thott doesn't have rewards at this time, however it gives an 18dps or so 1H Sword or a Held in hand item with 7int. Will try to get names and links later. - Taco
The baron spawns after doing the Fathom Core and drops an item to start this quest.
