My friends and I are wanting to run a Dungeon World game soon. We are all big on survival, grimdark themes, etc and DW is fairly open in how to portray the world and setting applications but everything I am reading and hearing so far states that it is heavily focused on high-ish fantasy with how classes are constructed and such.
How can I can use the game's mechanics, rules and systems to apply a survival feel to the game and make the players feel like everything has a cost and death is right around the corner without planning.
How we are defining grimdark:
A grim and dark tone, a sense of realism (for example, monarchs are useless and heroes are flawed), and the agency of the protagonists. (Wikipedia)
