Scrying

Lady Idunn meets with you and takes you to a stone path leading to a lake. Loki recognises the lake as a powerful scrying mirror. It must be activated and you, mortal, are best suited to the task of channeling energy into it.

Idunn will now travel to the right, and you three will go left so you meet at the viewing circle. The spires along the lake's shore are anchors and you must wake each and do it quickly.

You stepped through some acid clouds and yet your shoes seem completely unaffected. Loki points out that there is a spire representing each of the realms of Yggdrasil. You complete your task and return to Idunn

The water has gone clear and you can direct the platform with your movements. You can see the ley lines of Vanaheim in the mirror. Idunn says they look as they should, as do the ley lines of Asgard.

Idunn shows you that the Alfheim ley lines appear muddier and have moved out of place. These are troubling signs. Ley lines across the other realms have also shifted. These are worrying signs.

Perhaps Surtur is causing this, but Idunn prefers not to speculate yet. The ley lines of Svartalfheim seem less strained, and Loki speculates about Malekith. Thor alerts you to a black fog creeping across the lake. You need to stop the mirror!

You may rest but you should shelter away from the lake. Someone noticed the scrying, likely the one who caused the warping of the ley lines. This is also why the Bifrost cannot function. There is no way home until the ley lines are untangled.
