A Blade in the Dark

Background
''Delphine believes that dragons are coming back to life and the next one will resurrect near the town of Kynesgrove. Once I've convinced her that I'm Dragonborn by killing the dragon, she promises to explain who she is and what she wants with me.''

Quick walkthrough

 * 1) Talk to Delphine
 * 2) Locate the dragon burial site
 * 3) Kill the Dragon Sahloknir
 * 4) Return to Delphine

Delphine
Talking to Delphine will make her explain that dragons are coming back to life and asking her more, she will also reveal she is thinking the Thalmor are behind it. The Dragonborn is then asked to prove that they are indeed Dragonborn by killing a dragon. She believes that the next dragon to come back to life will do so east of the town of Kynesgrove. She will then give the choice to either travel to Kynesgrove together or go there alone.

Sahloknir
Upon reaching Kynesgrove, Alduin will be hovering over the grave. Alduin is performing an act to bring a dragon back to life and cannot be killed or injured at this time. Once he is finished, the dragon Sahloknir will arise from the grave site. Sahloknir needs to be killed.

A follower, along with Delphine will be useful for distracting Sahloknir. This fight can be made easier by attacking Sahloknir before he has been fully revived by Alduin. This way his life can be reduced before he is able to fight back.

Sahloknir and Alduin are engaging in a lengthy conversation during and after the resurrection, even addressing the Dragonborn themselves before combat occurs, and rushing in to combat will cause this dialogue to be skipped.

After killing Sahloknir and absorbing his soul, talk to Delphine. The quest "Diplomatic Immunity" will begin, requiring the Dragonborn to make a choice to either go with her back to the Sleeping Giant Inn in Riverwood or meet her there later.

Resurrection dialogue
Alduin: Alduin: Sahloknir: Alduin: Alduin: Alduin: "You do not even know our tongue, do you? Such arrogance, to dare take for yourself the name of Dovah." Alduin:

Trivia

 * If the Dragonborn does not immediately return to the Sleeping Giant Inn with Delphine, then she will wait in The Bannered Mare in Whiterun until they return to Riverwood.
 * If the burial mound has already been discovered, there is an extra dialogue option with Delphine, stating that the Dragonborn already knows where it is located.
