Without warning, one of the accursed vomit fiends stuck directly against the base of the stairwell itself. If any dwarf had seen it coming, they would have met it at the edge, or just outside of the curtain wall - but somehow, it managed to penetrate the primary defense. With a violent huff, similar in spirit, no doubt, to the formation of the creature, the green monster filled the interior of the curtain wall with a buffet of deadly vomit dust.
In a single blast of its breath (if you could even call it that), two dwarves are killed and four others injured. Id Whisperstrongs, one of the Quakedented recruits, and Shorast Towndye, last of the Bookpuzzled clan, perish when they are thrown against the steel curtain wall headfirst. As the surviving military bears down upon the blob of vomit, another deadly green cloud rises to the north - the fiend did not come alone.
Mercifully, the attack is resolved without further injuries - the warriors destroy the monster who had already attacked, and the one in the north dies to a blast of its own vapor. Injuries suffered, however, render the military effectively defeated. A few dwarves, including the prince himself, suffered several broken bones. All those who took part in the battle, however, suffer from a kind of chronic dizziness - likely a result of exposure to some terrible contaminant brewed in the cornucopia of bile in the interior of the green monsters. Every dwarf suffering from dizziness has left his post to rest in the infirmary, leaving the entrance to the fortress, and the construction of the temple in hell completely undefended.
A squad was kept in reserve for just this occasion. The Silvery Princesses, who have been training in the dome for years, are finally given the order to make the descent. Led by Ézum Openeddoors the Robust Stoker of Lances, and the other three members are of no small note: Nomal Biglabors the Lush Convent of Dwelling, last of the lashdwarves, now wields an adamantine shortsword with equally deadly skill; Érith Minedtribe, one of the only two surviving dwarves of the once mighty and prolific Gearguild clan; and of course, Cog 'Murdershot' Archwayward, recently elected mayor, daughter of the duke Kogsak Murdershot and queen of Weatherwires.
