Yess!!!! I've been waiting for this from you for ages! Always spot on stuff, hitting head on the nail!! I especially enjoyed that these desert encouters actually suits a campaign specific to a desert setting rather than just some quick flavour drizzle in a travel montage. Personally when I've run desert campaigns, my favourite has always been "sandsharks". I homebrewed sharks to have burrowing instead of swimming speed and then set them loose amongst the party's camels or other mounts when traversing the dunes. Describing an uneasy camel trying to escape what from afar just looks like extra shimmering sand. Shimmering sand that just keeps on getting closer and closer until sharks jump up from the dry sand!
