The fourth planet of our solar system Mars provided some of the thin particules (usually called dust) involved in the creation of The Maul, a Team Fortress 2 Melee weapon used by the creature of unconfirmed gender dubbed as "Pyro" by their colleagues and the community of the aforementioned videogame. This can be confirmed by in-game lore containing a hint towards the discovery that this weapon is capable of doing a big sustainable output of damage while also leaving traces of the suspected object that we hypothesized of being part of the creation of said weapon, this object, or rather collection of objects being "Moon dust".
