Even though Dragonborn constantly has to fight dragons in random encounters or as part of quest lines, sometimes you need to act more extraordinary. As part of “The Fallen” quest, players will have tofind out more about the location of Alduin, and Odahviing can help you. However, Odahviing is a giant dragon, and the only way to get some information is to trap it inSkyrim.
At first glance, it may seem that capturing a dragon is suicide, but by gaining the support of Jarl of Whiterun, this will become possible. You will also learn that the dragon’s names are Words of Power used to summon them, which will be the key to capturing Odahviing.

How to Capture Odahviing in Skyrim
Before you can trap Odahviing inSkyrim, you must meet a few prerequisites. As we said earlier, the first thing Dragonborn must do is enlist the support of Jarl of Whiterun, which is only possible after completing the Season Unending quest. However,if you killed Paarthurnax, you must move on in the Civil War questline until Jarl of Whiterun agrees to help you.
Once you have fulfilled this requirement, you will learn that the dragon’s names are Words of Power that can be used to summon them. This will allow you to learn Call Dragon shout and become bait for Odahviing. The next step for Dragonborn is totravel to Whiterunand visit Dragonsreach. Discussing the plan with Jarl Balgruuf the Greater will be the final stage of preparation, after which here are the steps you should follow to trap Odahviing inSkyrim:

At this point, Odahviing will no longer be able to escape and will be more amenable. In exchange for its freedom, it agrees to guide the Dragonborn to Skuldafn to Alduin.Subsequently killing Alduinand completing the quest line will make Odahviing respect your power. In turn, this will lead to you getting a loyal dragon you can summon as an ally, so this quest is worth the effort.
