Treaty of Gradkeep was an attempt to finally make peace among the kingdoms of Daggerfall and Sentinel during the War of Betony. Lord Graddock managed to convince both monarchs to come together and sign a treaty.
The terms of peace were discussed, agreed on, and set to paper. The terms were excessively generous. Camaron had agreed to give up some of his rights to Betony in order to placate the madness of Lysandus and bring peace back to the Iliac Bay. However, it turned out that it was a trick, the treaty was miswritten on purpose, so that Camaron would sign the terms he hadn't agreed upon. Thus the castle of Reich Gradkeep erupted into bloodbath, and the war continued.
