The rulebook includes a section -- 22.214.171.124, if you're interested in its wargames-style organization -- entitled "Difficulty of Being a Beggar." It reads in part:
Because of their handicaps and very low status in the Young Kingdoms' society, it is not recommended that beginning players attempt to use Beggars for their adventurer characters. If you have randomly determined that your adventurer character is a Beggar, you may roll again on table [126.96.36.199] Class Background if you wish.Maybe it's final, definitive proof that I'm as mentally deranged as some have claimed, but I think that's one of the more awesome bits of text I've read in any gaming rulebook lately. Makes me want to run an all-beggar mini-campaign set in Nadsokor.
However, those players who enjoy a challenge may get a special kick out of attempting to beat the system and win with a character who is blind, deaf, or partially crippled. Any triumphs won with such a character would be correspondingly greater than those won by normal characters. If you do choose to play a Beggar, you have my condolences and best wishes.
