High, thick walls surround a fairly small, but still bustling, town. The solid rock walls are breached by a narrow gateway, wide enough for but a single caravan to pass. Surmounting the gateway is a row of iron bars, their tips lovingly adorned with spikes that bear the appearance of lethality -- though they are raised now, it seems they would be easily enough lowered when needed.
