Character backgrounds:

The green-clothed brother & sister: 

After losing all of their money in a bet, the brother & sister seek to find the extremely valuable gold coins of legend, supposedly in this dungeon, only to join others in their journey...

The knight:

Once his wife is stricken with a very deadly illness, this knight sets out to find the ancient artifacts said to be capable of summoning the great healing dragon, that according to legend, can heal any illness or wound. Thankfully, he joins others along the way who help him to quicken his search.

The undead man:

Previously a horrible king, apparently dead for many, many, many years, he is in search of his hidden gravestone and a candle that, in legend, once combined with the dead one's gravestone in a certain way, he might rise again. This deadly person joins others in his search, however, they don't know his true intention.
