Dungeon Crawler

There is a place underground where a Queendom ruled by a Lamia, a variant of the snake race.   Underground?   Yes, underground, it is the very last level of a DUNGEON.   There is always lies, betrayal, and strife in this land because this is THE LAND of the SNAKEMEN.   Killing someone is always legal in the name of a duel, with this, only the strong is free to walk this land.   This is a land where the strong rules and the weak obey as slaves.   What would happen if you are born as a slave in this land?   Does it mean you are weak?   How would you survive this land from the bottom?
