This access quest is part of the Splitpaw Timeline. This is a continuation of the initial access quest for the Splitpaw adventure pack.
The minimum level for this quest is level 20 and will scale with the player's level up to level 60; however, some instances do not scale beyond level 50. You can still complete the requirements for this quest beyond level 60, but you will not receive rewards.
All instances are persistent except for the Upper Tunnels. This means that if you leave or logout in the Upper Tunnels, you will end up back outside the entrance in Thundering Steppes and you will need to clear the zone again. You cannot clear the Upper Tunnels and then pull other people through an empty zone.
The Lower Tunnels is a persistent shared zone, similar to city zones. There is a mender NPC there, quest NPCs and zone entrances to the other Splitpaw dungeons. It is safe to logout in the Lower Tunnels, you won't be teleported back to the Upper Tunnels entrance.
Make your way down to the Splitpaw Den entrance (it is called Lower Tunnels when you examine the zone entrance). See the zone description for Upper Tunnels for details about the route.
If you have the ability to stealth, you can move through the Upper Tunnels without being detected and moving objects will not break stealth. However, the gnolls and other monsters can see through invisibility. Make sure you are not close enough to be damaged by detonating an explosive barrel, that will break stealth.
You must now gain favor with the gnolls. Once inside Splitpaw Den, you will find several gnolls that offer quests to you in the side rooms off of the center room (the one you enter first). You will gain favor by completing any three of the following five quests: (The other quests given inside splitpaw do not count)
When you have done three of these quests, you automatically receive a a glowing azure shard as a quest update. This allows you to teleport to the Splitpaw Den from any place in the world. You also gain a few other rewards (see below).
