Rahgot

Rahgot is one of the eight Dragon Priests, and his name is similar to Rahgol which means "rage" in dragon language.

Background
Rahgot is believed to be one of the last remnants of the Dragon Cult around 1E 139. He led a small cult in the secluded monastery of Forelhost high in the Jerall Mountains.

A legion of King Harald's soldiers, commanded by Skorm Snow-Strider, discovered the hidden stronghold of Dragon Cultists and laid siege to it for several weeks. Once the main gate had been breached, Rahgot and his cultists retreated into the interior of the monastery and collapsed the main stairway to block access to the refectory.

Rahgot devised a plan for the cult to commit mass suicide in the main chamber, this was in hope that if Skorm and his men did eventually break through the main door, the sight of the mass suicide would deter them from searching for other survivors within the monastery and thus Rahgot would survive.

He ordered his alchemists to make large amounts of Deathbell poison for the cultists to ingest and also proceeded to poison their own water supply. Dissent was dealt with brutally; when Rahgot's chief alchemist questioned his orders for mass suicide, she was murdered.

The mass suicide was eventually carried out. Rahgot ordered the burial of the children's bodies and the remaining cultists died in their beds after taking the poison. When Skorm took the fortress, he saw the aftermath and proceeded no further. It is unknown what happened to Rahgot other than when he died he was sealed in a sarcophagus within the refectory.

Siege on the Dragon Cult
Rahgot can be encountered within the Nordic ruin of Forelhost during the quest "Siege on the Dragon Cult".

Notable items
Upon defeat, he drops Rahgot - one of the eight mysterious Dragon Masks located throughout Skyrim. Collecting all eight masks is a requirement for the unmarked quest to restore the Dragon Priest Shrine.

Combat
Rahgot can be very challenging even for a high level player as he is encountered with a good number of leveled draugr. A good strategy to counter this would be to sneak attack the Draugr and then confront Rahgot. Using the Slow Time shout when Rahgot is emerging from his coffin can also allow you to land a few early blows.

Trivia

 * If you come back to Forelhost a year after defeating Rahgot, he will rise from his sarcophagus without his mask on and will be titled: Dragon Priest instead of: Rahgot.
