Who doesn't like dragons?
Cult of the Dragon Infiltrator
You have infiltrated the ranks of the Cult of the Dragon. Having spied on the organization for quite some time, you are familiar with its inner workings and customs. You have a second identity as an initiate of the cult, enough of a facade to blend in as a simple grunt or servant.
You have studied dragons and their lore for many years. you can automatically identify locations built or used by dragons and can identify dragon eggs and scales by sight. If you fail an Intelligence check to recall lore relating to dragons, you know someone or some book you can consult for the answer unless the DM rules that the lore is unknown.
