Dragon rider is really a Dragoon (Fighter) archetype with added Leadership feat for out-of-combat buffing and healing.
Flavor-wise: Pariah belongs to a long-line of fighters who have bonded to "dragon" mounts (actual creature doesn't have any spells or sla) and together they have a life-long bond. They combine their skills and knowledge to craft magicks from artisan generation techniques. Unfortunately, due to the "change", the dragon mounts cease to exist and the dragon riders continued their tradition.
Is this acceptable? Leadership feat to have normal cohort who would grant overland flight on a mount which may be available to buy in the guild market.
Hi,
I am very interested in joining your campaign as a dragon rider.
Pariah, a venerable retired and forgotten Hammer and artisan attempts to reclaim his life's meaning by immortalizing himself as a legendary hero. With the assistance of a very enthusiastic and knowledgeable halfling helper, Ruby Goodbottom, the old fighter is transformed and lays an intricate plan to achieve his ultimate goal. Hearing rumors of young Forager's excursions, Pariah, the old fighter who lost his way and even forgotten his own name, hopes his answers lie outside the walls of the Artisans Guild. Pariah is rejoined by his dragon companion Torro, and the three set off to join the hired adventurers and to once again serve the Guild.
