Gray Assassins

The Gray Assassins are a group of people who, as of 843 PD, had been killing members of the Grim Verity for the past several years. They are also surmised to be behind an attack on Zephrah, six years prior. When they die, their remains turn into a dark gray liquid. Their motivations are unknown.

Before Campaign 3
In 837 PD, six years prior to Campaign 3, a group of assassins clad in dark gray leather attacked Zephrah. It was assumed to be an attack on Keyleth, Voice of the Tempest. In this fight, Orym's husband Will was killed. After Keyleth killed the assassins, the remains disappeared, as if they had melted. About six years later, shortly before, Jarret Howarth heard from his old friend Oshad Breshio that assassins matching a similar description had killed the Lumas twins, and passed along this intelligence to the Air Ashari via his employers, Percy and Vex'ahlia De Rolo.

Campaign 3: Bells Hells
At the beginning of Campaign 3, Orym arrived in Jrusar, Marquet to investigate. Breshio, who had been gravely wounded trying to protect the twins, provided Orym with his account, as did Roe Estani, a friend of theirs who had been present yet untouched in the attack. While their accounts agreed with Orym's experience, they were unable to provide more information on these assassins. However, Estani later told Orym that the twins may have been targeted due to their connection with the Grim Verity, and gave him a letter for another member of the Grim Verity, Ebenold Kai.

The name "Gray Assassins" was first stated by Hondir, also a member of the Grim Verity, in explaining why he had been in hiding. He told Bells Hells that half of the Grim Verity had been killed in the past decade. Imogen meanwhile realized that her dreams of Otohan Thull fit Hondir and Orym's descriptions, as well as Birdie Calloway's description of "terrestrial folk" working with the Unseelie Court on a plot concerning Ruidus in the Feywild. She confirmed with Hondir and Birdie that Otohan was indeed a member of the Gray Assassins. They also mentioned that another one of the leaders was an older elven man.

Orym confirmed that the assassins who attacked Zephrah are identical to the echoes that Otohan creates with her backpack. It is unknown if Otohan is the sole source of these assassins, or if there are others.
