Port description
"The sun beats down like rain. Occasionally, the rain beats down like rain."

Port description
"The Canal emerges in the little lake called Avernus. A warm breeze ruffles blue waters. You and your crew shelter like vampires from the light, with awnings, curtains, broad-brimmed hats. Poplars, birdsong, the warmth of the Campanian sun."
