Embrace the Drylands
When building your character, consider how their place in the Drylands impacts their aesthetics and approach to the world. Find reasons for them to love the land despite its harshness as they work desperately to protect the region from the monsters trying to tear it asunder.
Face the Unstoppable
In this campaign, your character stands against creatures taller than the largest buildings, whose destructive power is only matched by the most devastating natural disasters. Decide what makes your character particularly equipped to destroy colossi and, more importantly, what's personally at stake for them should they fail.
Navigate Your Faith
The Drylands are a land of extremes: it's extremely hot, extremely harsh, and extremely easy to die. Folks approach religion the same way. Some people believe that the gods never existed and the stories about the origins of essentia are just marketing and grandstanding. Others continue to worship the Forgotten Gods, attributing a spiritual aspect to their use of essentia. Still others believe essentia is a profanity and commit crimes to close up the mines in the name of the New Gods. Consider the beliefs your character held before the rise of first colossus and how they might have changed since.
Ride Like the Wind
Just about everyone born in the Drylands can ride a mount from the moment they can walk, and newcomers are expected to learn quickly. Unless you choose a feature for your character that provides an animal companion or applicable spell with benefits, their mount will not change their mechanics or give them an advantage in combat. They can, however, use their mount to pass between towns and portions of the desert with added ease and speed. The colossal children of a vengeful god are on the rise, and the party has no time to waste.
