After some debate and verbal parrying, it's agreed the trolls will show them the path to a new paradise...but they are betrayed, and the new world turns out to be the hot, barren desert. Their way barred behind them, they've no choice but to move forward, into the unknown.
This heartbreaking story reminded me so much of the Wolfriders and the Trolls: http://www.reuters.com/article/2014/09/20/us-usa-immigration-texas-border-idUSKBN0HF01920140920 It especially made me think of Woodlock and Rainsong, and their children.
Part of our illegal immigration problem in America is the "coyote", a criminal who preys upon poor and desperate people in different parts of Central America. Once across the border, the illegals may be left to suffocate in a locked truck trailer, or released many miles from civilization, to die of thirst and exposure.
(There's been much debate about illegal immigration in our country lately, but regardless of our varied opinions, we don't control the situations that people are trying so hard to escape.)
