Kerafyrm was awakened by <Seal Team> on April 13, 2022. The Warders no longer spawn in Sleeper's Tomb on Green.
Kerafyrm's Lair, also known as Sleeper's Tomb, is a dark dungeon located beneath the icy wastes of Velious, and was used by the First Brood to imprison the dragon Kerafym. Entrance to this zone requires a key from the Sleeper's Key Quest.
Eons ago, there was no such thing as the Claws of Veeshan or Ring of Scale -- dragons from all over Norrath were a part of the same clan. At some point, two dragons of different color decided to mate. Resulting from this union was Kerafyrm, a baby crystal dragon and an ensuing war amongst the dragons. In a successful effort to end the war, the First Brood imprisoned Kerafyrm in a tomb deep beneath the wastes of Velious, leaving four warders in place to guard the now-dormant crystal dragon.
Jaled'Dar, in rebellion against the Claws of Veeshan, wanted to bring the Golden Age for the Wurms to Norrath and decided that The Sleeper had to be awakened. However, he was slain in a great battle with the Iksar and now rests in his spirit form in the Dragon Necropolis. Due to his death, he needed to enlist the aid of Norrathian adventurers to further his cause. If Kerafyrm was indeed awakened, he will rampage from his tomb, through the icy wastes, and into Skyshrine.
Before sleeper wakes, all npcs see invis, named golems have less of a chance of dropping primals. [1]
After Sleeper wakes, no npcs see invis, if a primal drops, the chance of which one is equal instead of weighted, ancient sentries no longer flurry. [2]
The entrance to ST is found in Eastern Wastes at -7000, 0, roughly.
The exit to ST can be accessed by being fully shrunk and using a Stalking Probe or other similar means of casting an eyeball spell while being flush against a wall. Then click on the exit spire. This is especially useful if you find yourself past the trapdoors where the exit is otherwise inaccessible.
