Seukegeu, a horse's lower body and a human upper body, was the most trusted spearman under Diploel, who was originally the ruler of Weidete and a Heysha (a hybrid of Hey and prehistoric animals). However, Seukegeu, enchanted by Morgan, killed Diploel, and eventually, with Diploel's death and the rebellion of the Skurami, the castle of Weidete turned into the Tower of Darkness. Now, Seukegeu, due to the credit of killing Diploel, serves as the most trusted soldier under Morgan.
