My characters:
Eric Magus, the Warrior Priest: Eric, son of Grandol Magus (my favourite mage character player from Avernum 1 - 3 and Blades. I guess he is a bit of an old man (lol) so I didn't have him in this), wants to take on his fathers heroisim. He remembers to when his father (Age 20)got exiled down to Avernum and assasinated Hawthorne, then (Age 70) defeated the Empire with help from the Vahnatai, and (Age 120 (he is classified the oldest man ever alive both on the surface and in Avernum)) then went up to the surface to let Avernites go back up. He wants to be that way, too.
Shelly Magus, the Priest: Shelly is the husband of Eric, and joined him when they first met in Warrior's Grove. She has recently dyed her hair brown.
Feodoric Griefman, the Mage: Feodoric is a mage who has been through the history of Avernum, or at least he claims it. He says once Avernum was called 'Exile', and that he found the mystical pool of the 'Geneforge'. His team members find a bit coo-coo, but Feodoric is a great friend to them.
HrrMrr, the Fighter and Archer: HrrMrr knew Grandol (see Eric), as Grandol was HrrMrr's tutor. Grandol found him in Warrior's Grove, and took him on to a peaceful island to train. HrrMrr talks amazingly clear English, and also know a few basic spells.
I'll share a few stories of these guys later
