As you approach the temple, you hear a gutteral growl emenate from the darkness of the open portals. Four hairy and horned bow-wielding humanoids walk out, each with the lower body of a goat. They each nock an arrow and watch your approach with unease as a voice bellows from behind them. "I smell... humans..."
Heavy footsteps are heard approaching the temple doors. "First she sends her pets, then she curses me so that I may not use the greatest of my magics, and now she sends human assassins." The gutteral growl is heard again and grows angrier.
"I will slay her assassins, and I will wear their bones as jewelry." Footprints appear in the grime of the temple steps, although the walker is not visible to the eye. "Then, I will go to her glade, and take her other daughters like I have taken away her eldest then give them to my servants to do as they wish. I will burn down her ancient oak and spread its ashes across the rivers of this place and make this wood my own."
The four minions of the creature snicker, becoming more confident in their master's invisible presence. "I will do this with ease, for I am Morduk, third son of Krill the Binder, slayer of Ghul Dat, and enslaver of the dryad Trieste. Turn away, mortals, else look upon your death." So saying this, Morduk releases his invisibility and appears in the middle of his four archers. It's an ogre, but one wielding a greatsword and with a surprising amount of intelligence shining behind his eyes.
