Acridostrasz, also spelled Acridistrasz, is an eager young red dragon and former guardian of Grim Batol under the command of Garshilan, leader of the Red Dragonspawn Patrol. Brann Bronzebeard came across him while exploring Grim Batol during his journeys through the Eastern Kingdoms. Acridostrasz told Brann Bronzebeard that the red dragonflight is "guarding a secret that living creatures are not meant to know".
Acridostrasz is fiercely loyal to his queen, but he has a tendency to involve himself in mortal affairs. Acridostrasz heard that a powerful black dragon, disguised as a troll, lurked within a small troll encampment to the south of Grim Batol. Acridostrasz knew that his prominence in the red dragonflight would rise immensely should he defeat a black dragon in battle. To that end, he sought a band of adventurers to journey to the troll enclave and confirm or deny the rumor. The young wyrm hoped the adventurers would find out if the black dragon did indeed hide with the trolls, and not to attack it if it did; they were simply to report back to Acrodistrasz so he could deal with the creature. He would have performed the investigation himself, but it would have taken him away from his duties.
Several years afterwards the red dragonflight guardians of Grim Batol began to fall ill, some dying, others going mad and needing to be put down by their brothers and sisters. The red flight then abandonded Grim Batol.
