The Folly Crusade
Crusaders: 3d20=2+15+18
Sandstone Qhanganate: 3d20+2= 22+15+11
As the Crusaders leave their homelands, they encounter their first and foremost enemy: attrition. Though Duke Slugimex spent years rallying the faithful to his cause, he organized little in the way of logistics. Starvation, beasts of the wild and the burning sun of Eightstone's Desert has burned its way through the crusaders, and after a seven-month march, the famished vanguard arrives in the lands of the Gras Qhangan. There, they are immediately ambushed by fast sandstone archers, riding their spiders. The vanguard is annihilated, leaving the rest of the army weakened.
As the army regains it's energy by pillaging and burning their way through the sparse settlements of the Sandstone Qhanganate, they are continually ambushed, beaten and raided by the Nomads. This prevents military action, though the Nomads themselves are still vastly outnumbered by the massive army of crusaders, and refuse to commit to a full scale assault.
After a month, the Crusader Army finally starts charging. Though every battle is a meat grinder, ambushes await them around every corner and the Nomads refuse to submit to the rule of their former oppressors, the army makes a slow and steady progress. After carving out a small realm, the admirals decide to stop the offense and instead focus on holding the line.
Soon, discord breaks out between the higher ups of the Crusade. As the state is too far from either the Slugman Duchies or the Hrilithian Celestial Empire to properly be administered by them, a new leader needs to be chosen from the ranks of the Crusade. Added to that is the fact that the farms many crusaders were promised, turned out to be arid tracts of land, filled only with sand, rock, and thorny vegetation. Civil unrest seems to tear apart the 1st Crusader State before it is even properly established. For now the impressive military manages to hold it together.
In a surprise turn of events, the 1st Crusader State finds itself guaranteed by the Dorathian Kingdom. Though the Dorathians care little for the politics and religion of the nation, they see it as a perfect buffer state between their nascent coastal colonies and the Nomads.
