I recently learned about divine intervention too which is cool.

It's also neat that there's a Tribunal Temple equivalent, Almsivi intervention.
spoiler advanced strategy They're not just for returning to the nearest settlement. With the the ability to cast both and enough knowledge of exactly where the Imperial Cult and Tribunal Temple shrines are in relation to each other, you can sometimes alternate between casting them one after another to leapfrog around the map.
For example, say you're at the northern tip of Vivec and you want to get to Balmora. Almsivi Intervention from there would take you to the Vivec temple. But doing a Divine Intervention first would take you to Pelagiad, and then Almsivi Intervention from there would take you to Balmora. ::: :::
