In this lesson, we wrote two series of worked examples.
Orc siege
We hadn't written a fantasy example for ages, so we used this image of orcs attacking a human city and gave the orcs a new name.

Military dolphin
The second series of examples was based on 'seaside town stalked by shark' type stories, but with a different vibe.
