He was 8th level AIR, they had 13 PCs and NPCs in the 7th-11th level range to ambush it.
From the Story Hour:
"The next morning, Sigurd ordered the guards to have a statue constructed to poor Arf, then the battered party headed for Pan Charak, reaching the barony after nightfall. There at Castle Brax they consulted with the young Baron Abu Brax, and met a band of five Thrinian Knights come to aid Pan Charak against the hordes of Gaxmoor - and kill the red dragon troubling Carrisqui Town! Aos got on very well with a female member of their company.
Two days later the party departed for Carrisqui Town, along with the Thrinians, reaching Dulleaberg in two days, where Sigurd reported to the Margrave. Then they departed for Carrisqui Town, and the dragon...
At Carrisqui, Sigurd berated the Mayor for his lack of loyalty to the League, and somehow extracted the magical greatsword of Vorloth from him!
30/2/2738: Dragonfight
Lorne, Ori and Orstadt waited hidden beneath the dragon's sacrificial cows in an open field southeast of Carrisqui Town. The others waited in the trees. Lilliana summoned two celestial stewards of Carthea, and beseeched their aid - which was granted with the proviso that Lilliana travel to Imarr and free the city from Overking Tarkane's tyrannical rule!
The red dragon Wormscather was spotted, approaching from the southeast. His fiery breath incinerated most of the cows, but as he landed to feast, the adventurers struck. Ori, struggling with a barbecued cow, got to his feat, only to be flattened by the angry dragon. The Thrinians charged on horseback, but their lances proved ineffective against the dragon's magical Shield. Sigurd flew up to attack from the flank, doing some damage. The party closed in on the dragon - fully thirteen adventurers to face the beast! The celestials dispelled the dragon's protective magics, giving the party the chance to draw blood. It bit, clawed, beat its wings and slapped its tail furiously, injuring many, but Sigurd hacked furiously, while Aos tried to leap on its head, and Xyzzy threw spells. At length the wounded dragon took flight and flapped away. Larius, Lorne and Sigurd followed flying, doing further damage, but at length it outdistanced them, returning badly wounded towards its distant lair. The party had triumphed, and claimed their reward, but the dragon still lived and had best be tracked down before it recovered, or it would go ill for Carrisqui..."
