Picture this: Lord Ventris has a court wizard. Scatterbrained guy by the name of Pappellion. He forgets his spells, our Pappellion, so he uses parrots to remember the vocal bits. One day, disaster strikes!
A little boy is SUCKED INTO A PORTAL after a spell goes awry (don't worry, he's fine, just living with birds now). Presumed dead, Pappellion is tried as a murderer and sentenced to JAIL. His beloved birds are killed before him. Now he's out and he wants REVENGE
So what's a wizard to do? Just what anyone would do, given the circumstances. He summons Guano the Great, dread pigeon of fire-breathing fame, directly into Lord Ventris's courtroom! ...Or he would anyway, if it weren't for those damn necromancers protecting the Lord.
That's where you come in. I won't spoil all the secrets, just know that there is INTRIGUE and POLITICS and UNDEAD OWLBEAR SKELETONS in this adventure about a giant pigeon.
