Bend Will

 is a Dragon shout in.

Description
The Bend Will shout is learned during the main quest of add-on,. Unlike most shouts, its three words have different effects. The first word allows one to control animals and the stones, such as the Earth Stone in Solstheim. The second word allows the Dragonborn to control mortals. The third word allows the Dragonborn to control dragons, allowing he or she to ride them. Hermaeus teaches you the last 2 parts of the shout. You get the last shout to tame dragons before the very end of the quest line.

Notes on Dragon Riding

 * When used on a dragon, it will land and allow you onto it's back. Unfortunately however, you will not be able to fully control the dragon in flight, only direct it.
 * Tamed dragons respond to the Dragonborn's instructions (i.e fight). Often calling him/her Thuri meaning master.
 * You may fast travel while riding a tamed dragon. However, you cannot travel directly to a major city (i.e. Solitude).
 * If directed to attack another dragon, the two will engage in aerial combat.
 * Dragons can be directed to attack NPC's such as hold guards.
 * Using Bend Will on an airborn dragon will cause it to land directly next to you.
 * Some time after dismounting, the dragon will fly off. However, if the player uses the 'wait' function for a long time, the dragon may become hostile again, and proceed to attack the player.
 * If the dragon dies, you will be dismounted, much the same as with the horse.
 * This shout does not work on most named dragons, such as Alduin, however it does work on Odahviing.

Landing after the shout is used

 * "Hail thuri, shall we fly together?"
 * "I am at your command."
 * "How may I be of service, thuri?"

When directed to land

 * "Yes thuri, Wah Golt [to ground], I will land at once." 
 * "I will look for a spot to land."
 * "As you command, zu'u fen daal wah golt [I will return to ground]."

After being dismounted and the shout wears off

 * "I am no longer needed."
 * "My service is complete."
 * "You cannot command me forever." 
 * "I must leave you now."
 * "I have served you for long enough."

When directed to attack

 * "Mu Fen Krif  [We will fight] "
 * "As you command."
 * "At once, Zu'u Fen Al [I will destroy] "

When there are no targets to attack

 * "Krosis, The land below is empty of prey."
 * "Drem. There is no prey here."
 * "I sense nothing nearby."

When told to do something impossible

 * "Krosis thuri, that is impossible."
