Whistler

Whistler is a town in Canada.

By 2012, it was the location of an Assassin cell consisting of its leader Janice and two other operatives. On 12 September that year, Janice requested reinforcements from Gavin Banks. At the same time however, a team of Templar agents led by Daniel Cross attacked the Assassins' hideout. Despite this, at least one of the Assassins survived.
