While not exactly an ally, Azazel is still Graxian Graxian's patron. A succubus from Avernus and part of Zariels army.

Silver Dragonborn. Won over his fellow townsfolk with his brawn and good humor. Leader of Caer-Konig. Drinks to much.

Half-elf. Commands Easthaven's militia.

Commoner in Targos. Keegan Velryn is missing his husband, who went missing when he guided some adventurers to Kalvin's Cairn.

Dannika Graysteel is a half-elf scholar and The Arcane Academys representative in Icewind Dale.

With an The Arcane Academy as the group's patron, they gain the following perks.

Compensation. The academy pays each member of your group 1 gp per day, or enough to sustain a modest lifestyle. 

Documentation. You have identification denoting your affiliation with the academy. This association carries clout in scholarly or artistic circles. The academy also secures documentation, letters of introduction, and travelling papers if your work requires them. Such documents grant you special status, such as access to forbidden regions or neutral standing in embattled areas. Such identification isn't always a boon, though. In a land frequently plundered by foreigners, your documents could mark you as nothing more than aggrandized looters to some.

Research. Research is part of your group's job, but your patron also has abundant resources to facilitate such efforts. You can call in a favour to delegate the work of researching lore to a colleague, contact, librarian, or research assistant. You're responsible for covering expenses incurred as part of this research, and the DM determines its success or failure.

Resources. Academies host libraries, museums, record repositories, and training facilities, and you can use them to further your work. You can call in a favour from faculty members to access resources not available to the public—dangerous relics or magic items, spellbooks, gear, and the like. Additionally, you can consult with the faculty of your academy as the experts in various fields.

Training. Because you're associated with the academy, you receive a discount on any education you wish to pursue. When you undergo training as a downtime activity, you pay half the normal cost, assuming the academy teaches that subject. Training in languages, musical instruments, and other tools is also available, at the DM's discretion. In addition, you can gain proficiency in the Arcana, History, Nature, or Religion skills by this method, as if you were learning a language. A character can learn only one of these skills in this way.

Silla is a healer in the employ of the Aracane Academy. She can support the adventurers if the need arises.

Tormund works for the Arcane Academy, and is assigned more physical tasks than Silla, and that can come in handy for the adventurers.
