Writings of Wonder is a Legendary Tome that produces 2 Troves of Wonders when they are fully charged. Unlike Common Tomes (that can be used as often as you like without cooldowns), these tomes can only be used once a week, although, they provide more rewards than Common Tomes per individual use.
Due to their removal from Trove of Wonders, they have become extremely rare nearly becoming unobtainable through normal means (other than the possibility of becoming a rare drop in Chaos Chest loot rotations). People who already have this tome can still use it.
