Archmage Emon Thermack founded and led the house until his demise.
As one of the three houses, Darksbane held sway in 1/3 of the trade of Brightport. They traded in potions, magical materials and crafting supplies.
When House Silverclaw hired Group 2 to steal their Golden Dragon, a series of events unfolded that would be the downfall of Thermack and the House.
After virtually everyone in the house was killed, the group took over, renamed it House Dragonkeep and eventually handed control of it over to Tessia Grimnas.
