Dilge is a young half-orc wizard and half-brother to Philge. The Dragon Friends first encounter Dilge while shopping for magical items in Waterdeep. He and Philge had not seen each other in some time prior to the events of the show.
Dilge is very enthusiastic about reconnecting with his half-sister and participating in the Dragon Friends' adventures. Unfortunately his head is bitten off by Davin Tyrril's black dragon in the aftermath of confronting the cult in Waterdeep during Shut Up, I Look Great (1.10).
