Adam Page is probably best known in the RPG Blogging community as @blindgeekuk. He wrote a phenomenal amount of material for the Winter is Coming blog carnival last month, and is a regular contributor to the Daily Encounter.

In addition to the introductory material, there are two themes: The Shadow Caller and the Shadow Seeker.
