To elaborate this is how it works in the same context. The character picks up sponsored magic and gains Channeling (un/seelie magic) and ritual (un/seelie magic). Thus they can cast any spell (evocation or thaumaturgy) that fits within their un/seelie theme (for unseelie that would be air, cold, darkness, decay, death and for seelie light, fire, earth, growth, life). As per channeling and ritual the character does not gain specializations, but does get focus items/enchanted items.
