10 Hidden Gaming Easter Eggs With POWERFUL Rewards

The Witcher 3's Blood and Wine DLC lets you and Geralt travel to the fairytale-like duchy of Toussaint, where chivalry is far from dead and every corner has a knight or two running errands for their duchess.

In fact, there is even an Easter egg in the region that references history's most legendary knights, and Geralt can even join their ranks for an incredible reward.

"There Can Be Only One" is a secret side quest in Toussaint in which Geralt comes across a mysterious hermit on Lake Lac Célavy. 

The hermit will ask Geralt to prove he possesses five virtues of chivalry in exchange for a sword hidden underneath the lake.

Proving the five virtues requires you to complete the quests in Toussaint in a way an honorable knight would, which is why if you haven't been acting morally throughout the game, you may not be able to claim the prize.

Those who can prove their honor get to fight the monk, who later reveals herself to be the Lady of the Lake, a mystical being worshipped by Toussaint's knights, and then grants you her legendary sword, Aerondight.

This is not only a reference to the famous tale of Lancelot, but it's also a nod to Geralt's past dealings with the Lady in the previous games.
