Murderer Brothers

Archae, Bismarck and Corax are Kenku who are outcasts from the Shadowfell. They were slaves of Ikthal Tourín before arriving in this world. Once they were free, they set to the arduous task of building a new portal with the intention of returning to the Shadowfell. They laboriously collected appropriate gemstones from nearby regions and captured the souls of Red Rock residents to empower their magic. Wary of their former master, they used warding magic to hide what they were doing and collected servants to assist them, chief among them Andrew Groose, aka The Rhino.

Once they completed the new portal's construction, they still needed two key components, the 12 gemstones empowered by souls and Ikthal's Bell. During a competition in Magnamar they found a dwarf named Isaac Obsidian who, after a few friendly drinks, admitted that his parents had been killed by their kin for dabbling in gemcraft, which held bad opinion for reasons Isaac did not know. Intrigued by his connection to their craft, they tasked the Rhino with learning more about Isaac and his group "Thorne's Orphans".

Bismarck successfully stole Ikthal's Bell from the Bronze Knuckle Brothers, allowing him and the Rhino to travel long distances in short time. At the beginning of the Red Rock Campaign the only gemstones they had left to obtain were Amethyst, Tourmaline and Ruby. The Amethyst they desired was found in the vault of Isaac Obsidian in Magnamar. The Tourmaline was discovered embedded in the head of Qarkragora, the Fen Hydra. The Ruby was embedded in Lady Hylia of Magnamar's armor.
