Tammuz is an Elder who was worshipped as a Sumerian god of vegetation. He is Palamedes' master, and he is portrayed as an Elder who has power over forests and trees. In his Shadowrealm, Sherwood Forest, he rules dryads, hamadryads, nymphs, and other nature spirits. He also has some power over time, given to him by Chronos, used to make Palamedes and the Green Knights immune to the time differences between Earth and the other Shadowrealms. He sent Saint Germain, Palamedes and Shakespeare to Marethyu's Pleiostoic Era Shadowrealm.
