Through the Shattered Sky is a horde quest in Icecrown Citadel per the Shadowlands expansion of World of Warcraft.

When Sylvanas shattered the Helm of Domination, she was touched by the power it released. I can sense the echoes of that power, and I know where she has gone. If you wish to rescue your leaders, the shattered helm can open a path. It cannot bring you back, however. That you must do on your own. The risk is great, <name>, but there is no other way. We will begin the ritual at once.

Quest objective:

Complete the ritual at the Frozen Throne to open the rift into the Maw.

Through the Shattered Sky

In the center of the glowing blue vortex are several shards. You’ll need to take each one and walk to a specific area to place the specific shards (check your minimap).

Originally, when playing the beta, you could use abilities to make you move faster, but as of the Shadowlands release, it seems you’re unable to use them anymore. Thus, you’ll be walking quite slow.

Once it’s just the helm left, interact with it to open the rift.

Completion Rewards

Note:
Some of these rewards will vary depending on what class you’re playing, as well as the level you’re currently at. Thus, I don’t give the exact rewards.

Gains:

  • Currency
  • Experience
