Reward: 250 Renown, 5000 Gold.
A year has passed and your life has become a little bit normal than before. One day, when visiting your mother's grave in Oakvale, you are contacted by the Guild Master and told that there have been disturbing news from Scythe, a half-undead hero guarding the far north. Go to the Lookout Point and see what's going on.
Scythe tells you that the world is threatened by the awakening of terrifying creatures known as the Summoners. He needs help dealing with this threat in the Northern Wastes, and the only way to get there is to obtain an artifact known as the Fire Heart. You will find it behind the awakened Primal Demon Door just next to the boasting portal. Don't hesitate to enter.
Inside, in the Fire Heart room, you will be forced to solve a simple puzzle. Each time you step on one of the squares on the floor, you change its color - to orange (sun) or blue (moon). In every round you have to change all the squares into one type. If that will be blue, one of the Prophets will die, if orange - he will be freed. It's up to you, again, whether you want to save or kill them. You'll get the Fire Heart after a few rounds either way.
