From House of Hozz
The lair of The Dragon villain. It lies at the base of the old Great Tree and houses a vast hoard of treasure the Dragon has amassed over the millennia. The dragon's hoard predates the current Great Tree, and contains various artifacts from the age(s) before, some of which he believes the Zarth forged in the heat of Incaoolin himself.
There are various entrances, but all are magically sealed against any living creature passing without "giving up its life", which kills any TwinWorld native (all TwinWorld life forms display monolithic vitality, that is, their life can not be seperated from themselves without killing them?). This enchantment is broken by human bloodletting, as humans can release only part of their "life" through their blood.
