Y'all know I love the Blighted Rook trope.
Imagine the Shadow Dragon Rook who is Lucanis's soulmate. They saved Minrathous, the city and people he made an oath to protect.
The distance between them and Lucanis only fuels their guilt. They're trying to help Treviso however they can.
A missive arrives from Teia and Viago asking for help because darkspawn are causing issues in a particular part of the city that currently was housing people displaced by the Blight.
Everyone in the Lighthouse happens to be away doing their own thing. So Rook does something stupid. They go to Treviso to hunt darkspawn. They manage to kill the darkspawn but they get injured and Blighted while doing it.
Rook has enough sense to know their only hope now is the Wardens, so they drag their wounded ass into the Crossroads. They end up collapsing in the Crossroads. Only luck allowed Davrin to find them in time, on his way back from Lavendale. He drags them back to the Wardens who put Rook through the Joining.
Rook survives and begs Davrin not to tell anyone else. Davrin, knowing their leader is being a maker damned idiot, tells the Veilguard anyway.
