Cleansing the Temple of Oblivion

Do you know the history of the Temple of Oblivion?.. This temple was built to the glory of the twin spirits: the ether of light and the ether of darkness. These spirits were distinguished by a peaceful and noble disposition. But the war of the gods came to Dratan, and the blooming land turned into a desert. Monsters and robbers have entered the temple. They killed the priests and desecrated the altars. The spirits failed to protect their worshippers. The twins' grief was so great that they sank into oblivion. Taking care that innocent people did not wander into the terrible temple, seeking shelter from the storm, the ethers surrounded its walls with a spell that makes travelers think that they are facing a mirage... My predecessors preferred to pretend that the temple did not exist and did not exist, but I am determined to expel the monsters and restore its former greatness. Let's start with the hedins. I hope you will be able to overcome them.
