Ragruz

Ragruz is one of the highest ranking devils of the Brass Embassy in Stoneharbor. So far the party had little interaction with him, but (indirectly) he has significantly affected the Avalanche's life:
 * The Avalanche learned that, similar to Rhelora, Ragruz often makes contracts with mortals where they provide some form of service for him and may keep their souls if they fulfill their obligations (e.g. barkeep Henry in the Brass Embassy). Note that it is likely that he tries to trap them in their contracts, similar to Rhelora).
 * Ragruz appears to be of either equal or higher rank than Rhelora.
 * He was the one who revealed the Avalanche's role to Lucca Alvari in the stealing of the Edict from the Library of Eternal Fire. It is unclear whether he did so in order to advance some long term infernal plan, or whether it was part of a contract he made with Alvari, or perhaps he just wanted to sabotage Rhelora.
 * Rhelora mentioned several times that in case of her demise Ragruz would inherit her contracts, including the one with the Avalanche.
