HistoryVery little is currently known of Diana and she prefers it that way, having yet to reveal even the rest of her name to her party members. She joined Group 1 as they were traveling to Durnhollow at Nathaniel's behest, claiming she needed information from Carter. The next few days did not ingratiate her with the rest of the group. Even though her persuasive and magical talents helped the group form an alliance with Durnhollow among other things, the Tiefling’s cold demeanor and disdain of humans produced some bad blood.

Diana helped the group throughout the attack on the Overwatch, playing an important role in strategizing how to get in the walls. Once they were in the city her magic proved crucial to the party’s success. While in Carter’s castle she appeared to have knowledge of the archmages and was easily able to comprehend what she could glean from Loreweaver's journals before pocketing them. The appearance of Emon Thermack clearly shook Diana, causing a spontaneous eruption of flame from her hands. For the rest of the battle she seemed intent on nothing but destroying Carter and Thermack, and when the archmage was slain she collapsed onto the ground. She gave a rousing speech after the battle that helped to soothe tensions between citizens of Overwatch and the coalition army. After the city was settled, she continued with the group for a while but after a deal with some Drow seemingly went bad, she disappeared and has not been seen since.
