Vassir-Didanat Cave is an abandoned ebony mine found in the Ascadian Isles region. The entrance of the mine is due south of Balmora and east of Shulk Egg Mine on the eastern side of the Odai River. From Balmora, head southwest along the river until reaching the rope bride crossing the Odai River just past Shulk Egg Mine. Turn to southeast and cross the rope bridge, continue heading in the same direction until reaching the mine. The twisting mine tunnels open up into several rooms with multiple ebony nodes. There are various monsters roaming the mines as well.
