Noblewoman of Wintermoss

Lady Glenderyn is the wife of Arthur, and hosted Mile and Adelka for dinner, when they visited Wintermoss.

Noblewoman of the Iron Crown

Lady Kotara is a noblewoman from Frosthaven. First encountered in the Water Temple, she agreed to let Mile go unhindered, as he had saved the life of her close companion, Juno.

Later Mile thwarted her attempts to capture the Garden Tortoise, resulting in Kotara being swept away in floodwater during the climax of Season 2.

Mile is now in possession of Kotara's private correspondance, which gives him some leverage over her... for now.

Archer

Juno took part in the Vespasia's attack on Rumbelow's skyship, and somehow survived the crash, turning up badly injured and feverish weeks later in Wayrest, where Mile (not knowing her identity) helped to save her life. Her face now bears a faint scar from the fever that nearly killed her.

First encountered in Amberley, Saffie is excited to guide her first travellers, however she is easily distracted by various things, including food, and her own reflection.

Princess of Nightfall

Scarlett is convinced that she has the common touch, and that she has blended in easily with the villagers of the Farmlands. She was anxious not to be found by the men in blue uniforms, who turned out to be soldiers of the Iron Crown.

Mile and Rumbelow delivered Scarlett to Nightfall, where she remains in the protection of the great wizard Morgenstern.

Man of business

Grimshaw is a mysterious stranger who appeared in Amberley shortly after Mile, and attempted to claim the Kingstaff from him. Scarlett recognized him as a servant of the Iron Crown of Frosthaven. 

After pursuing Mile across the Farmlands and the Heartlands, Grimshaw was onboard the Skyship Vespasia when it crashed near Inkwell. His fate is unknown.

Gambler

Appearing mysteriously in Foxdale after Grimshaw's departure, Chambon's suspicious behaviour marked him as a possible threat, and it was soon confirmed that he was an agent of the Iron Crown. 

Tasked with stealing the Kingstaff from Mile and Scarlett, Chambon was eventually thwarted, falling over the edge of the flying island of Inkwell.

Captain of the Peregrine Nation

The bold and dashing Rumbelow is a skyship captain. Summoned by Adelka, he granted Mile and Scarlett passage to Inkwell.

After engaging in secret missions for Morgenstern, Rumbelow reappeared at the end of Season 3, just in time to rescue Mile from the Nightfall Arena.
