Dungeons & Dragons

Almost 4 years into our campaign, and we've had some roster changes, but currently we have:

A mad scientist artificer that has built a giant beetle mount, a hellfire powered flamethrower and just made some doc oc arms out of a god's prosthetics, as well as some prosthetics of her own.

An assassin halfling turned cleric of luck. She was too optimistic to be into killing people for money but enjoyed the training. She tries to use her skills now to aid people suffering from bad luck.

A snerfniblin passing himself off as a regular gnome, all of the players have figured it out, but the characters pretend not to know. He's a wizard having a crisis about finding a purpose to his life.

A warlock genasi of mixed teifling heritage whose patrons used to be a council comprised of all of his children, but after the last time he died he came back with a new mysterious patron and has decided it may be safer to just keep his soul in this coin that it's trapped in now in case he dies again.

Finally the GMPC who is their mcguffin/eternal escort quest: a elderly teifling author who was previously a failed adventurer. He only knows cantrips, has proficiency in all the INT stats and all his friends are dead. He supplies lore about the world, gives them a reason to go strange places and gives them something fragile to have to protect.
