There are four different Dwemer Lifts that can be found in the Wyrmstooth worldspace.
Dimfrost - Steam PoolsEdit
Likely the first Dwemer Lift unlocked during the adventure, this allows rapid access to Dimfrost from the volcanic area at the center of the main Wyrmstooth island. It is roughly located between Hunter's Shack and Twinpeak Tower.
Dimfrost Luminatory - WyrmstoothEdit
Unlocked after the second confrontation with Vulthurkrah, this allows to exit the dragon's lair and return to the surface. It is located south of Wulfmere's Watch, and north-west of the Dimfrost - Steam Pools lift.
Belonir's Borg - WyrmstoothEdit
Unlocked after taking the plunge in Belonir's Borg, it allows to go back to the surface. It is located east-north-east of Belonir's Borg, and just south of the unmarked jetty that allows to travel back to the main Wyrmstooth island from the Belonir's Borg island.
Frostwind Bastion - WyrmstoothEdit
Unlocked after reaching Frostwind Bastion, it provides a shortcut back to the surface. It is located north of Frostwind Folly, and east of Chillbone Camp.
