From The Heretic Knowledge Vault
Samuel is one of the inhabitants of the Santuariel-like town of Snamish, a sanctuary for half elves set in the mountains of Veracia. He has a brief moment in the sun when PCs Sister Rose (whose late husband was from Snamish), Argus, etc., come to town. He helps PC Lillith and NPC Alia with a minor errand that turns out to be more significant when Lillith and Alia debate Lillith's vegetarianism while performing it, one of several incidents that convince Lillith that, half elf sanctuary or not, Snamish isn't her kind of place. Eventually the party moves on, and that's the last we see of him.
A few other NPCs in Errant Road also bear the name Samuel; see ER:Samuel (disambiguation) for help in sorting out who's who and where they appear.
