The Meiyerditch Laboratories are a set of winding tunnels beneath the Sanguinesti Region where the vampyres practised haemalchemy until they were suddenly shut down by Lord Drakan. Various gruesome experiments were conducted there on humans and bloodveld. The northern end of the tunnels connects to the tomb of Ivandis Seergaze.
During the quest Darkness of Hallowvale, the player visits the laboratories in search of possible research that may aid The Myreque in their fight against the vampyres, and during Sins of the Father, the player and Safalaan visits further beyond for additional research.
Access to the complete laboratory is granted after the player kills the mutated bloodveld that appears during the Sins of the Father quest, though players are recommended to complete the quest until acquiring Vyre noble clothing for easier laboratory access.
In the southern part of the dungeon, near the mutated bloodvelds, there are 3 log respawns and tinderbox. In the eastern part, crawling hands can be found as well. The entire area is also multicombat and the Dwarven multicannoncan be used here thus making it an excellent place to kill bloodvelds with a cannon.
The entrance to the true Blood Altar is located within the northern part of the dungeon, a blood talisman or blood tiara is required for players to enter the ruins. Players may also access the altar through the blood rift in the Abyss. In this area, a nearby skeleton can be searched for a tatty note.
The entrance to the Meiyerditch Laboratory is in the house with the slashed tapestry, which is south-east of the location you arrive at once exiting the Meiyerditch mine.
There are various ways to get there:
One of the fastest ways to reach the Meiyerditch Laboratories is to ask the closest Vyrewatch to be sent to the mines, and then exiting. Once you exit, follow the path to the house with the slashed tapestry and climb down the stairs to enter the Meiyerditch Laboratories (See image: "Route to the Meiyerditch Laboratories").
Access to the bloodvelds is only possible after killing the mutated bloodveld that appears during the Sins of the Father quest, as otherwise the door will not open.
After Sins of the Father, players can also do the following:
Use a Drakan's medallion and teleport to Darkmeyer. Run north, east, south, and west to reach the cracked wall, follow the path to the house with slashed tapestry, climb down the stairs.
Teleport to Canifis, go down the Myreque Hideout trapdoor (south of Hair of the Dog Inn), go south through the secret wall, take the first cave east, travel directly south through the next cave entrance shortcut until you reach the Meiyerditch Laboratories cave system. This shortcut requires 93 Agility and 78 Mining along with a pickaxe the first time it is used. The shortcut must first be cleared by bringing a pickaxe to the laboratory side of the shortcut specifically and clearing the shortcut's tunnel. Subsequent uses just require 93 Agility and can be entered from either side. Alternatively, fairy ring code DLS can also be used to access the Myreque tunnels before the shortcut.
