From publisher blurb:
The Orb of Envy is a short adventure designed for five 6th-level characters and features social interaction, exploration, and combat. Scaling suggestions are included for weaker or stronger parties.
Alina, youngest daughter of a noble family, showed signs of magical aptitude in her early teens and was apprenticed to Master Wizard Roondar Quinnius. Over the years, the princess and her family exchanged many letters, and Alina often visited. She has served her parents and their court well, but always returned to Master Roondar to continue her studies.
A little over a year ago, Master Roondar took possession of an emerald green scrying orb. Having several such orbs already, he gave this one to Alina to study and learn the arts of divination. Unfortunately, the orb was cursed. The more Alina experimented with it, the more the curse transformed her until she became a green dragon in form as well as temperament. Eventually, she killed Master Roondar and claimed the tower as her own.
The heroes have gained a reputation for being good folks. Alina’s parents haven’t heard from their daughter in six months. With rumors of a dragon floating around, they have tasked the characters with bringing Alina safely home.
The heroes hear rumors of a green dragon that recently took possession of a wizard’s tower just outside the town of Howling Rock.
The heroes are passing through the town of Howling Rock and hear from the locals about the dragon menacing the area, and the missing noblewoman the townsfolk consider “their princess.” The dragon leaves the town alone except for demanding books, jewelry, and pastries but it’s also eating the local sheep, and now the town has run out of books, jewels, and flour.
The heroes witness the green dragon fly overhead, headed for a foliage-wrapped tower in the distance.
