Hollow Halls

6 Hollow Halls on the map of Embervale, at levels 10 to 45, in 6 regions. Bone Keys, crafted by the Collector, open their doors in Revelwood, the Nomad Highlands, the Kindlewastes, the Albaneve Summits and the Veilwater Basin; there is none for the Springlands. Some chests inside need Ectoplasm to open.
