This establishment serves hot beverages and simple food. Unusual in that most of its clientele are changelings, it is a place for quiet conversation and meditation. Song of Skin changelings perform guided meditations in which a dozen people travel through a journey of different bodies, forming and abandoning a dozen different forms. The proprietor is a changeling named Silence. It is quite likely that Silence is in fact a group identity shared by multiple changelings; his alignment and abilities could change each day (his statistics are left to the DM). Silence enjoys listening to the tales of travelers, and has a special service for favored customers: he produces and sells psionic tattoos. It is up to you to decide what he has available at any given time and what it will take to convince him to sell.
There are many questions surrounding the Song of Skin. Why do the Inspired allow Silence to sell tattoos? What is his motivation? It's quite possible that Silence is a creation of the Thousand Eyes and passes all information along to that group. On the other hand, perhaps Silence is a spiritual creation of the changelings of Dar Jin who serves as a focus for their belief in the Path of Inspiration. Either way, the Song of Skin could serve as a sanctuary for changeling dissidents such as Keshraa the Fallen.
